1.2.8

Paul changes on xsh_flexcomp-NIR:
I refined this a bit by setting up a reduced set of parameters that get
annealed (scenario=9) that correspond to the parameters were identified in
the flexure analysis that I did. This means that there is not such a large
group of parameters getting (in some cases arbitrarily) adjusted, but the
residuals achieved are just as good.                 

                 Changed PRO.SCIENCE detmon products from T to F

                 Fixed problem PRO.CATG of master bad pixel map of xsh_mflat
                 In case no input master BP map is provided and is provided an
                 input BP_MAP_NL_ARM from detmon recipes.

                 Now all response recipes apply response computed on merged 
                 frame and not the one computed order by order to flux 
                 calibrate science products.
1.2.7
                 Flux calibration is computed using the response computed i
                 on the merged spectrum.
                 Paul improved the flexcomp for NIR:

It now does an anneal which is essentially the same as xsh_predict with the default scenario=3. Regarding prism temperatures, this uses the same logic as for the shift, i.e. parameter change is calculated under the assumption that the phys mod is evaluated at the temperature of the AFC. (In practise the NIR temperature is very stable anyway).

1.2.6
                 Added BP_MAP_NL_arm (raw format-from detmon cross-instruments 
                 recipe) as possible input of xsh_mbias, xsh_mdark xsh_mflat

                 required to compute spectral format resolution

                 in order to unify code across response and scired recipes.
                 Removed dependency xsh_localize_params in xsh_util_ifu_offset
1.2.2:
                 Fixed error xsh_lingain if RP map is provided in input 
                 Fixed robustness line detection on ARC SLIT & IFU frames
                 Fixed typo in PIPEFILE names in case SKY frame appears 
                 before object in offset observations

                 Allow to have input wave and slit maps in 
                 xsh_scired_slit_staere and xsh_respon_slit_stare to save 
                 computation time.

                 Fixed error on variance propagation in IFU mode.
                 Fixed error switching off sky subtraction in xsh_scired_slit_stare
1.2.1:
                 Changes from Paul on physmod and flexcomp:
                 1. Further correction to 2x2 binning such that:
                 a) n_d=n/2 [n_d is floating point double binned co-ord, 
                    n is floating point un-binned co-ord]
                 b) bins are alligned such that double bin pixel N_d contains 
                    unbinned pixels N=2N_d-1 & N=2N_d
                 c) centre of double binned pixel N_d is now N_d-0.25
                    Unbinned mode is NOT affected.

                 2. In flexcomp the offset of AFC measured line positions 
                    relative to phys mod WITHOUT temperature adjustment 
                    (affects all prisms and UVB focus) is also calculated. 
                    By comparison with the offset relative to phys mod with 
                    temperature adjustment the mean effect of the temperature 
                    adjustment can be estimated and used to bring poly mode 
                    (which has no temperature adjustment) and phys mod mode 
                    order tables into agreement.

                 Fixed bug response computation in offset mode.
                 Swap order of orderdef UVB tags so that it is used only D2 
                 in case the user provides both of them.
                 Added Bary & Heli corrections  computations (during order 
                    rectification)
1.2.0:
                 Fixed problem on line detection in case of bad bad pix map
                 Updated reference FITS.
                 Fixed problem in computing  QC WAVECAL MATCHLINE in xsh_follow_arclines.c
                 Set model temperature as the one or slit-arc frame.
                 Fixed mem leaks

1.1.7:
                 Fixed crush wavecal in case of missing input file and corrected man page. Added mode info on 'ON' product.
                 Replace XSH_MOD_CFG_ARM value by XSH_MOD_CFG_TAB_ARM. 
                 This affects xsh_util_physmod (allows to have a unique 
                 TAG for the starting model CFG both in xsh_predict and 
                 xsh_util_physmod so that one can use the same reference 
                 frame, for example in gasgano (that reads from the frame 
                 the PRO.CATG if set).
                 Allow only uniform value estimation for pre/overscan estimate.
                 changed input tag XSH_MOD_CFG-->XSH_MOD_CFG_TAB in xsh_util_physmod

1.1.6:
                Included gain correction in response computation in order to 
                be able to cross calibrate stars acquired with different gain 
                settings. That means the response is in electron units.

	 --compute-map=FALSE
	
Regis : 23-03-09:
Functions updates :

a) subtract_sky_single
 * add parameter --sky-method (BSPLINE) MEDIAN or BSPLINE
 * add parameter --sky-median-hsize (7)
 * add parameter --sky-slit-edges-mask (0.5) in arcsec
 *  The function includes now the sky subtraction under the object,
    the mask of the object is used.
b) localize_obj
  * add a parameter --localize-method=MANUAL or AUTO
  * add a parameter --localize-slit-position(0.0) in arcsec
  * add a parameter --localize-slit-hheight(0.5) in arcsec
  * The manual mode create a localization from given parameters
c) xsh_extract
  * remove from parameter --extract-method NANUAL
  * remove parameter --extract-slit-position
  * remove parameter --extract-slit-height
  * We remove the manual extraction because we have manual
    localization !!

Recipe updates :

xsh_scired_slit_stare
  * add parameter --compute-map
  * change the recipe code to be complient with new DRL
		 document !!
  * The new parameter introduce the compute of the slit_map
		  and the wavemap from the dispersion solution

Laurent-05-02-09:
	xsh/xsh_rectify.c: Fixed a bug in shifting with nodding keywords
	 (conversion from arc seconds to slits was wrong - typo error,
	 multiply instead of divide).
	recipes/xsh_scired_slit_nod.c: Suppressed the background
	 subtraction.
	

Laurent-23-01-09:
	xsh/xsh_data_dispersol.c: Fixed trailing bug: there was still
	 a cpl_polynomial_eval instead of xsh_order_list_eval (in function
	 xsh_dispersol_list_to_slitmap).
	xsh/xsh_rectify.c: Added transformation of model calculated x,y
	 into binned x,y.

Laurent-22-01-09:
	xsh/xsh_create_wavemap.c: The file name of the saved file was
	 hard coded. Now uses the argument to xsh_create_poly_wavemap.
	xsh/xsh_data_dispersol.c: Fixed bug in
	 xsh_dispersol_list_to_wavemap (used cpl_polynomial_eval instead
	 of xsh_order_list_eval, needed to take into account the binning).
	xsh/xsh_follow_arclines.c: Fixed bug in
	 find_tilt (used cpl_polynomial_eval instead
	 of xsh_order_list_eval, needed to take into account the binning).
	xsh/xsh_subtract_sky_single.c: Changed handling the binning of the
	 wavemap versus binning of the input frame:
	  If wavemap binning == input binning Then use the wavemap as it is
	  Else If wavemap binning == 1x1 Then rebin the wavemap according
	   to input binning
	  Else issue an error message and stop the recipe.
	recipes/xsh_wavecal.c: Added parameter "compute-wavesol". If
	 FALSE, a new wave solution is NOT computed and the wavemap is
	 computed using the input wave solution. In this case no residual
	 table product.
	xsh/xsh_parameters.c,h: Added function to create and get new
	 parameter "compute_wavesol" (used in xsh_wavecal)

Laurent-21-01-09:
	xsh/xsh_subtract_sky_single.c: Oops ! Had introduced a bug while
	 suppressing warnings.
	recipes/xsh_scired_slit_offset.c: Preliminary, not fully tested
	 but running version.

Laurent-19-01-09:
	xsh/xsh_subtract_sky_single.c: Introduced a re-binning of the
	 wave map. Note that the re-binning is made in a quite crude and
	 trivial way which implies problems at the edges of the orders.
	 Replaced cpl_polynomial_eval by xsh_order_list_eval to take into
	 account the binning.
	 Suppressed many warnings.
	recipes/xsh_scired_slit_stare.c: Updated messages.

Laurent-14-01-09:
	xsh/xsh_rectify.c: Fixed a bug in the calculation of slit limits
	 (function get_slit_min_max_nb): was 1/2 bin too large.

Laurent-13-01-09:
	xsh/xsh_localize_obj.c: Added some check (in function
	 xsh_localize_obj)
	xsh/xsh_rectify.c: Fixed bug in case of non 1x1 binning: one MUST
	 use functions "xsh_order_list_eval" instead of direct
	 cpl_polynomial_eval to do the conversion for binning.
	xsh/xsh_subtract_sky_single.c: Same bug fix. In addition one MUST
	 use the function "xsh_order_list_get_starty/endy" to do the
	 conversion for binning.

Laurent-12-01-09:
	xsh/xsh_subtract_sky_offset.c: Cleanup (suppressed unused static
	 function).
	xsh/xsh_subtract_sky_single.c: Suppressed check on unused
	 wave tab frame
	xsh/xsh_drl.h: Changed order of arguents in prototype of
	 xsh_subtract_sky_single
	recipes/xsh_scired_ifu_offset.c: Fixed bug (background subtraction
	 was done but the resulting frame was not used)
	

Laurent-09-01-09:
	xsh/xsh_data_rec.c: Something strange occurs (under Linux, not MacOs):
         the recipe xsh_scired_slit_nod crashs by segmentation fault -
	 for UVB not for VIS, in the function xsh_rec_list_free,
	 during one of the cpl_free calls.
         In order to allow continuation of tests, freeing of the rec_list
         is - temporarily - disabled until the problem is understood and
         fixed. The consequence is that there are some memory leaks in
	 all the recipes that use rectified frames (xsh_scired_... recipes).

Laurent-08-01-09:
	xsh/xsh_pfits.c/h: Changed definition of nodding keywords:
	 NODTHROW --> 'NOD THROW'
	 RELOFFSETX --> 'RELOFF DEC'
	 CUMOFFSETX --> 'CUMOFF DEC'
	xsh/xsh_data_rec.c: Changed function xsh_rec_get_nod_kw (nodding
	 data are double, not int)
	xsh/xsh_extract.c: Suppressed check on loc_table_frame; the
	 localization table is not used (yet) and in the case of IFU,
	 if used, we need a frameset of 3 localization table.
	xsh/xsh_data_wavemap.c: Cleanup (comments)
	xsh/xsh_badpixelmap.c/h: Added function xsh_bpmap_collapse_mean
	 used in xsh_combine_offset (if less than 3 sci frames)
	xsh/xsh_dfs.c/h: Added function xsh_dfs_split_offset (as there
	 are 2 different tags in the case of offset: OBJECT and SKY).
	 Modified function xsh_find_wave_tab_ifu: if only one wave tab,
	 it is "triplicated" (in standard we should have 3 different wave
	 tabs)
	xsh/drl.h: Added prototypes for xsh_subtract_sky_offset and
	 xsh_combine_offset
	xsh/xsh_remove_crh_multi.c: Added function xsh_combine_nod
	 (similar to xsh_remove_multiple). Introduced static function
	 xsh_remove_cosmics, used by functions xsh_remove_crh_multiple and
	 xsh_combine_nod (with a flag to make the fifference).
	xsh/xsh_remove_crh_single.c: Suppressed check on loc_table_frame,
	 not used yet and if we want to use it, needs a frameset in the
	 case of IFU.
	xsh/xsh_subtract_sky_offset.c: New source file containing function
	 xsh_subtract_sky_offset
	xsh/Makefile.am: Added xsh_subtract_sky_offset.c to the list of
	 source files.
	recipes/xsh_scired_ifu_offset.c: Completed version. Not yet fully
	 tested, but at least it compiles :)
	recipes/xsh_scired_ifu_stare.c: Added check on presence of Model
	 or wave tab.
	recipes/xsh_scired_slit_node.c: Cleanup (updated some comments)

Andrea-20/03/08
Performed a number of minor fixes reported in the comments to DRL 0.15: 
-all calib recipes: 
	fix small typos (mainly related to order table TAG 
	changes recently defined but not always reflected
        in man-page, fixed some static check warnings) 
	1s indiated in DRL0.15 report

Changed:
diff -r1.7 xsh_data_resid_tab.h
diff -r1.19 xsh_data_the_map.c
diff -r1.10 xsh_data_the_map.h
diff -r1.26 xsh_model_kernel.c
With the following purpose:
-when a column name is of kind 'prefix suffix' it is preferrable to have 'prefix_suffix' (as some data analysis software, like MIDAS, otherwhise have problems). Example 'Slit position'-->'Slit_position' in RESID_TAB_SLIT_arm
same for 'detector x'-->'detector_x' and 'detector y'-->'detector_y' (FITS file involved is THE map)


Changed:
diff -r1.67 xsh_utils.c
diff -r1.46 xsh_utils.h
-Added xsh_free_table
