Changes in 3.3.9	
	Crush of flames_cal_prep_sff_ofpos with CPL generated MSFLATs


Changes in 3.3.8
----------------
	Fixed several SPRs:
	DFS04196: Cleanup and improvement of uves_obs_scired for 2D extraction
	          (removed double '_' in FLUXCAL & FLUXCAL_ERRORBAR products,
	           standardized naming convention of science products for 1d
	           and 2d extraction following DFO requirements).
	
	DFS04196: ERROR file missing from 2d uves_obs_scired output
	DFS04274: cpl_tools_get_cputime failure in uves_cal_ordertrace
	DFS04283: UVES average extraction fails
	


Changes in 3.3.5
----------------
	Fixed several SPRs:
	DFS04051: Mis-Order identification in uves_cal_orderpos
	DFS04175: Poor order trace in uves_cal_orderpos
	DFS04255: Order trace failure for DICH#1 564.0
	
                  uves_cal_orderpos has been modified to add use_guess_tab
	          parameter to specify how to use the input guess table:
	
--use_guess_tab : If a Guess order table is provided this parameter set
                  how it is used:0: No usage, 1: use it to set
                  lower/upper Y raws where order are searched 2: the
                  order table try to fully match the guess. [1]


	
	DFS04195: New QC1 parameters in uves_cal_dark recipes:
	          QC REGi [MIN|MAX|AVG|MED|RMS] are generated on several 
	          regions evenly distributed on the detector. Those are
	          controlled by new recipe parameters:

  --qc_dark.reg.num_x   : Number of regions on X direction (where mean/med/rms
                          are computed). [4]
  --qc_dark.reg.num_y   : Number of regions on Y direction(where mean/med/rms
                          are computed). [4]
  --qc_dark.reg.box_sx  : Region X size. [100]
  --qc_dark.reg.box_sy  : Region Y size. [100]
  --qc_dark.reg.border_x: X distance from the left hand side detector's border
                          and the left hand side regin's bottom corner. [100]
  --qc_dark.reg.border_y: Y distance from the left hand side detector's border
                          and the left hand side regin's bottom corner. [100]
  --qc_dark.reg.when    : When QC analysis is performed. 
	                  0: on each raw frame or
                          1: on the master frame. [0]	                 
	

	
      DFS04196: Some cleanup on 2D extraction PRO.CATG and default file names.
      DFS04197: Added ERROR file on 2D extraction.

      Upgrade to CPL4.
      Added unit tests.
	
	
      Completed conversion of FLAMES-UVES to CPL and started testing. This
      part is not yet delivered as part of this release.

	
Changes in 3.3.4
----------------

        uves_cal_tflat +???: Added QC parameter INS.SLITi.NAME
	
	Updated to work with both CPL-3.x and CPL-4.x
       

Changes in 3.3.3
----------------

        Added support new format FLAMES
       

Changes in 3.3.2
----------------

        uves_obs_redchain: Minor bugfix: If both raw dark and master dark
	frames are provided, the master dark is not recomputed unlike before.


Changes in 3.3.1
----------------

	(released to public)
        Fixed typo in description of the parameter --plotter


Changes in 3.3.0
----------------

        Changed wavelength calibration tolerance from 0.07 to 0.6. The
	value 0.07 was too low for some (red) wavelength settings.


Changes in 3.2.3 (public beta-release)
----------------

        Catch possibility that ORDi OBJ POS is NAN (flux_tot=0) and set it to -1
        (normally it should be >0). This could cause execution failure during
        average/linear (response/tflat recipes) if line tilt correction
        was enabled.

        Removed the recipe uves_obs_spatred which is exactly the same as
        uves_obs_scired but with the option --reduce.extract.method=2d

        All recipes: Removed parameter --midas, which was used only by
	the pipeline developers for regression testing and is no longer useful.

        All recipes: Removed parameter --imager which was not really supported
	by any recipe anyway.

        Added check in reduction that the provided master flat-field's
	mean is not zero, NaN or infinity. In this case the recipe will
	fail, rather than silently succeed.

	
Changes in 3.2.2
----------------

        uves_cal_mdark: Disabled the thresholding of negative values to
        zero after bias subtraction.


Changes in 3.2.1
----------------

        uves_cal_orderpos: Avoid the detection of very short orders near
        the chip edge top/bottom which could not be reliably traced in
        the current scheme.        

        Optimal extraction: Changed spectrum error formula to take fully
        into account sky contribution. This causes a lower but slightly
        more accurate reported S/N.


Changes in 3.2.0
----------------

        Optimal extraction: Added support for setting extraction slit
        offset and slitlength. This allows extraction of multiple sources.

        Wavelength rebinning: Automatically correct for line tilt by
        interpolating the previously obtained dispersion polynomials
        at the measured object position

        uves_obs_redchain: Implemented option (--scired=false) to produce
        all master calibration frames but skip the final science reduction

        uves_cal_wavecal: Fixed execution error in the resolution
        computation which was not robust to the unexpected situation
        where the dispersion d(lambda)/dx had the wrong sign (due to
        fitting too few lines with too many polynomial coefficients)

        uves_cal_wavecal: Fixed execution error in the resolution
        computation which was not robust against negative error bars

        uves_cal_wavecal: Added QC1 parameter ESO.QC.NLINSOL which is
        the number of lines that were actually used in the wavelength
        solution. Added column "NLinSol" to line table containing the
        value 1 (0) if the line was (was not) used to obtain the
        dispersion solution

        uves_cal_wavecal: Changed default slitlength from 15 pixels to one
        third of the value defined in the arc lamp FITS header. This is to
        support flat-field correction in which case the noisy interorder regions
        should not be extracted.
        

Changes in 3.1.1
----------------

        Wavelength calibration: If the master flat and/or master bias is
        provided, the arclamp frame will be flat-fielded and/or debiased.
        If the arclamp was flat-fielded a modified line search algorithm
        is used, which takes into account the spectrum error bars. If no
        flat-field is provided the wavelength calibration works as before.
        
        Optimal/simple extraction: If the calling recipe
        (science/response/wavecal) is run with the --debug option, an
        intermediate FITS file 'simulate.fits' is saved to the local
        directory. It contains a simulated raw image created using only
        the extracted object + sky spectra + cosmic ray locations.

        Fixed value of keyword HIERARCH.ESO.PRO.REC1.DRS.ID from
        'uves/X.Y.Z' to 'cpl-X.Y.Z' (bug introduced in 3.1.0)

        
Changes in 3.1.0
----------------
        
        Optimal extraction, virtual method: Now uses sampling factor 10 if
        the estimated S/N is > 200, otherwise 5 (as previously)

        uves_obs_scired, uves_cal_response, uves_cal_tflat:
        added QC parameter ESO.QC.ORDi.OBJ.RPLPAR to estimate
        small scale oscillation amplitude

        uves_cal_wavecal: Increased robustness of the computation of the
        mapping between relative and absolute order numbers

        uves_cal_wavecal: Implemented option to use automatic polynomial
        degrees when fitting the dispersion solution. The default degree
        is still 5.     


Changes in 3.0.2
----------------

        uves_cal_orderpos: If an order table is provided as input, the
        recipe will no longer do a Hough transform but simply detect the
        orders defined in the input table. Orders are detected using a Hough
        transform only if no input table is given.
        
        Changed value of FITS keyword CRVAL2 in REDU products from 2049
        to 2113 in order to reflect the physical gap between the two red
        CCD chips.
        
        Minor bugfix in uves_cal_orderpos when determining the optimal
        polynomial degrees which, in rare cases, could be less than fully
        optimal. Impact: probably none.

        Science recipe: Bugfix in generation of the product
        WCALIB_SCIENCE_x which was erroneously flat-fielded.
        
        
Changes in 3.0.1
----------------

        Optimal extraction: Speed-up. Fixed bug that the extracted
        spectrum might be completely wrong if the object offset is very
        close to +- 15 pixels.
        

Changes in 3.0.0
----------------

        Optimal extraction, virtual method: The spatial profile is now fitted
        with low-order polynomials as function of (x, order), where
        previous versions assumed a constant profile, for efficiency
        reasons. This was needed to have good results also at very high S/N

Changes in 0.9.10
-----------------

        Changed computation of master bias QC parameters to exactly match
        what MIDAS' STAT/IMAGE does.

Changes in 0.9.9
----------------

        uves_cal_wavecal:
        - The continuum slope is now included in the Gaussian fit to
        emmision lines.
        - Default tolerance lowered from 0.6 pixels to 0.07
        pixels for support of the new reference line catalogue.
        - When obtaining the dispersion solution, outliers are rejected
        using kappa sigma clipping.
                
        Renamed recipe uves_cal_mkmaster_tflat -> uves_cal_tflat

        Reduced the overall execution time for uves_obs_scired by a factor
        ~2 (when using the default optimal extraction, virtual method).
        

Changes in 0.9.8
----------------

        Fixed bug that uves_cal_mkmaster_tflat execution sometimes failed when
        calculating QC.ORDi.DATA(MIN|MAX|AVG|RMS|MED) for first/last order


Changes in 0.9.7
----------------

        Fixed bug introduced in v0.9.6 that the REDL chip was processed
        twice for RED arm input.

Changes in 0.9.6
----------------

        Changed CRVALi in recipe products to not include the detector
        overscan and prescan areas

        Renamed the following recipes
          uves_mbias    ->  uves_cal_mbias
          uves_mdark    ->  uves_cal_mdark
          uves_physmod  ->  uves_cal_predict
          uves_orderpos ->  uves_cal_orderpos
          uves_mflat    ->  uves_cal_mflat
          uves_wavecal  ->  uves_cal_wavecal
          uves_response ->  uves_cal_response
          uves_tflat    ->  uves_cal_mkmaster_tflat
          uves_scired   ->  uves_obs_scired
          uves_redchain ->  uves_obs_redchain
        and added four recipes
          uves_cal_cd_align       : Measures Cross Disperser positioning
          uves_cal_mkmaster       : Same as uves_cal_mbias/dark/flat
                                    depending on type of input frames
          uves_cal_mkmaster_sflat : Same as uves_cal_mflat
          uves_obs_spatred        : Same as uves_obs_scired, but the
                                    extraction method defaults to 2d.
        
        Implemented workaround for bug in cpl_image_threshold()
        (DFS03433) that caused very large sigmas to be set to only 2**31
        in the rebinning step. This decreases the probability of
        infinities showing up in the final products

        Minor bugfix in computation of QC.OUTi.RON.MASTER and
        QC.OUTi.RON.RAW (+-10% outliers were not ignored, now they are)

        
Changes in 0.9.5
----------------

        INF + NAN no longer written to FITS files.

Changes in 0.9.4
----------------

        Optimal extraction: Fixed bug in sky subtraction: the sky term was
        forgotten when looking for outlier pixels. This seems to solve the
        problem of strong sky emission lines causing residuals in the
        object spectrum. Default sky subtraction method changed to
        "optimal" which has slightly better S/N than the "median" method
        used before.

        QC-parameters: ESO.QC.ORDi.OBJ.(SN|POS|FWHM) are logged also in
        average/linear extraction mode (previously: only when using
        optimal extraction). ESO.QC.EX.(NORD|XSIZE|YSIZE) added to some
        products of uves_scired and uves_response. Bugfix in computation
        of ESO.QC.OPTEX.YSIZE which is the extraction slit, not the
        image height.
        

Changes in 0.9.3
----------------

        Master flat recipe: No longer thresholds pixel values to zero
        after bias + background subtraction
        
        Added 'Select' column to wave.cal. product line tables

        Added option to select optimal extraction sky-subtraction method
        (median/optimal, default: median) independently from profile
        measuring method

        Added FLAMES recipes (preliminary) and renamed pipeline to FLAMES/UVES

    Bugfixes:
        Fixed CDELTi, CRVALi, CRPIXi, CTYPEi keywords to self-consistently
        describe the geometry of the BLUE/RED detector arrays. The 
        information about the orientation of products wrt input frames is
        not propagated which would probably require using the CROTAi keywords
        
        Fixed a 4 byte buffer overrun in rebinning step

        Made uves_physmod run when --debug=true

        Made optimal extraction more robust for extended objects

        The QC parameters ESO.QC.ORDi.OBJ.POS and ESO.QC.ORDi.OBJ.FWHM
        were swapped. Now they are correct
        
Changes in 0.9.2
----------------

        Changed guess line table PRO CATG from LINE_TABLE_* to LINE_GUESS_TAB_*

Changes in 0.9.1
----------------

        Implemented TFLAT QC test

        Implemented barycentric/heliocentric velocity correction QC parameters

        Renamed line table columns so that they have the same
        names (WAVEC, RESIDUAL, PIXEL) as in the MIDAS pipeline

        Fixed a problem in the stability check: From now on it runs only the
        uves_msrawxy section and table comparison and not all the rest.

Changes in 0.9.0
----------------
        Implemented QC parameters (physmod: stability check,
        wavecal: intensity monitoring, scired)
        
        Updated to CPL3.0 (faster polynomial fitting, correct
        default parameters when running with Gasgano, ...)

        physical model: fixed problems in QX X/Yshift parameter discrepancies

        Fixed a problem in physmod joining table (tolerance increased)

        Fixed a bug in uves_physmod_msrawxy in table selection which 
        occasionally generated wrong ORDERMAX values

        Optimal extraction: Automatically detects profile measuring method
        based on an initial estimate of the object S/N

        Optimal extraction: S/N increased by doing a second extraction
        using improved variance estimates based on the 1st extraction

        Significantly reduced execution time for sky subtraction

        Added support for master TFLAT_ and SCREEN_FLAT_ frames

        Added support for MASTER_RESPONSE correction

        Response recipe does not fail but reduces the standard star
        when there is no matching catalogue object (DFS02900)

Changes in 0.8.5
----------------
Added QC parameters
        - orderpos:  Added DET CHIP1 NAME
                             INS GRAT1 NAME
                             INS GRAT1 WLEN

        Support bad pixels in optimal extraction (to allow flat-fielding method = pixel)


Changes in 0.8.4
----------------
done normal
        Rebinning: The flux is resampled using a smooth interpolated
        profile. This reduces resampling noise.

done normal
        Find a way to make doxygen warn about functions with missing documentation

done normal
        Optimal extraction: Change sky flux normalization from 1
        pixel to full slit.

done normal - Add support of Moffat profile


done normal
        Optimal extraction: Compute table with observed profile
          prof(order, x, dy) = flux(order, x, dy) / extracted(order, x)
        (and with interpolated profile if possible)

done normal
        Test effect of no integration over bin on extraction quality

        Solution: This was tested on UVES.2000-02-12T06:06:55.689.rb which
        is a high S/N ~= 250, narrow, fwhm ~= 2-3 pixels, object, for which
        the effect of integration is expected to be biggest.
        1) MIDAS standard: small scale oscillations
        2) CPL standard (Gauss-Legendre integration over bin): no oscillations
        3) CPL no integration over bin: extremely similar to case 2). One has to
        look very carefully to notice the difference which is well below the
        inherent noise level.
        Conclusion: A lack of bin-integration does not cause the observed
        ripples, even for narrow, high S/N objects.

done low (maybe)  
        Make 'make distcheck' work      

done low (maybe)
        Make code portable to Mac
        Solution: The package is known to install and 'make check' on Mac.

Done after version 0.8.2
------------------------

Bugfixes:
- Optimal extraction halted if first/last order had no bins
completely inside the image (an introduced bug).
- Response/science recipes: Atmospheric extinction correction was randomly disabled, depending
on the contents of uninitialized memory (an introduced bug).
        
Internal/maintenance:
- Simplified uves_insert_frame (too long function)

New stuff:
done - (andrea) - Add basic routines to do QC log.
done - (andrea) - Add rules to support any recipe provided.
Done after version 0.8.1

done normal
        Removed test data from distribution

EXTRACT

done normal
        Optimal extraction: Update the profile measurement to decrease
        sample step size until we have an appropriate number of
        (non-rejected) measure bins

done normal
        Optimal extraction: Factor out gaussian assumption.

MASTER FLAT

done normal
        Support [MASTER_]DFLAT_xxxx frames
        Support [MASTER_]IFLAT_xxxx frames

done normal
        Use different default smooth windows depending on type of input
        frame (science or flat)
        

MASTER DARK
        
done normal
        Support [MASTER_]PDARK_xxxx frames
done normal
        The recipe (MIDAS+CPL) produces negative fluxes (trans-dark?).
        Is that really what we want?
        Solution: This was caused by bias subtraction where bad columns
        was corrected (no correction in dar/flat. Now, the flux is
        thresholded to zero.


Done after version 0.8.0

done high
        Check ~20 pixels difference in line table xdif ydif
        UVES.2000-03-12T09:51:16.834.rb
        Solution: This is likely caused by different detections by
        the 2d search/centering step. This can cause deviations up
        to 2x(search window size).

        Line table column aux has type double but is always an integer value.

        In a few cases (e.g. UVES.2000-03-12T19:24:03.552.rb) line table
        column Selplot contains garbage


Done after version 0.7.8
------------------------


GENERAL
done normal - rejected
        Remove MIDAS flags (?)
        Solution: It was decided to keep the MIDAS flags, as they do no
        harm (other than making the code slightly more complex) and they will
        probably be needed later
