UNDER DEVELOPMENT

The software package is currently being dramatically improved and updated.
This is a (very) old version, potentially with bugs.

Default: 814 ; N_MAX - Truncate catalogue at this shapelet parameter. ; ; KEYWORD PARAMETERS: ; POLAR - Convert to polar shapelet coefficents automatically on load, ; in reduced {r,theta} form (cf shapelets_polar_reduce.pro). ; MOMENTS - Calculate object shape moments (astrometry, photometry etc) ; automatically on load. ; DECONV - Read PSF-deconvolved catalogue (if available) ; PARITY - Rotate all objects automatically on load so that their ; ellipticity is aligned with the x axis then flip, if ; necessary, so that all their isophotes begin to twist in a ; clockwise sense. ; RESIZE - Rescale so that all shapelets use the same beta. ; ; OUTPUTS: ; shapecat- name of catalogue (shapecat structure) returned in memory. ; ; MODIFICATION HISTORY: ; Mar 04 - Split into shapelets_concatenate_shapecats by RM. ; Jan 02 - Written by Richard Massey. ;- ; Set up filenames if n_params() eq 0 then message,'USE: shapelets_read_shapecat_hdf,shapecat !' if keyword_set(filt) then filter='f'+strtrim(filt,2) else filter='f814' in_dir=shapelets_paths(2) ; Read in catalogues message,"Reading in shape catalogue of HDF north",/info if keyword_set(polar) then message,"Conversion to polars may take a few minutes",/info if keyword_set(moments) then message,"Calculation of objects' moments may take a few minutes",/info if keyword_set(deconv) then filter2=filter+"_deconv" else filter2=filter shapelets_read_shapecat,cat_n,'HDF-N_'+filter,$ moments=moments,polar=polar,/silent,parity=parity,resize=resize,n_max=n_max message,'Reading in shape catalogue of HDF south',/info shapelets_read_shapecat,cat_s,'HDF-S_'+filter,$ moments=moments,polar=polar,/silent,parity=parity,resize=resize,n_max=n_max ; Concatenate catalogues shapecat=shapelets_concatenate_shapecats(cat_n,cat_s) shapecat.name="HDFs" message,'HDF shapelet catalogues successfully in memory',/info end
