Commands in the CCD package

Below follows a brief summary of the CCD commands and parameters for reference. Except for the already existing command FILTER/COSMIC, the commands in Table 3.11 are initialized by enabling the CCD context with the MIDAS command SET/CONTEXT CCDRED. Parameters will generally obtained from the CCD keywords; however some of the keyword settings can be overruled by specifying them on the command line.

 

HELP/CCD [keyword] provide help information for a CCD keyword

INITIAL/CCD [name] initialize the ccd package

LOAD/CCD [instr] load telescope/instrument specific default

SET/CCD keyw=value [...] set the CCD keywords

SAVE/CCD name save the keyword settings

SHOW/CCD [subject] show the CCD keyword setup

 

REDUCE/CCD [in_spec] [out_frm] [proc_opt] (partial) calibration of one or more science frames

COMBINE/CCD exp_type [in_spec] [out_fram] combine CCD frames using catalogue input

OVERSCAN/CCD in_fram out_fram [sc_area] [mode] fit bias offset in the overscan region and correct

TRIM/CCD in_fram out_fram [im_sec] [del_flg] extract the useful data fro the ccd frame

FIXPIX/CCD in_fram out_fram [fix_file] [fix_meth] correct bad pixels using a pixel file

BIAS/CCD in_fram out_fram bs_fram correct input frame for the additive bias offset

DARK/CCD in_fram out_fram dk_fram correct the input frame for additive dark offset

FLAT/CCD in_fram out_fram ff_fram do a flat fielding of the input frame

ILLUM/CCD in_fram out_fram il_fram] do an illumination correction of the input frame

FRINGE/CCD in_fram out_fram fr_fram do a fringe correction of the input frame

FRCORR/CCD [in_spec] [out_spec] [xboxmn,xboxmx] [yboxmn,yboxmx] [clip] [losig,hisig] make fringe frame

ILLCORR/CCD [in_spec] [out_fram] [xboxmn,xboxmx] [yboxmn,yboxmx] [clip] [losig,hisig] make flat field illumination correction frame(s) (TBD)

ILLFLAT/CCD [in_spec] [out_fram] [xboxmn,xboxmx] [yboxmn,yboxmx] [clip] [losig,hisig] make illumination corrected flat field frames (TBD)

SKYCORR/CCD [in_spec] [out_fram] [xboxmn,xboxmx] [yboxmn,yboxmx] [clip] [losig,hisig] make sky illumination correction frame(s)

SKYFLAT/CCD [in_spec] [out_fram] [xboxmn,xboxmx] [yboxmn,yboxmx] [clip] [losig,hisig] apply sky observation to flat field

ALIGN/MOSAIC in_frm in_tab out_frm method,data [xref,yref] [xoff,yoff] [x_size,y_size] align the elements of the mosaiced frame

CREATE/MOSAIC in_cat out_frm out_tab nx_sub,ny_sub mosaic a set of (infrared) ccd frames

FIT/MOSAIC in_frm in_msk in_tab out_frm [match] [nxrsub,nyrsub] [xref,yref] [x_size,y_size] align and match the elements of the mosaiced frame

MATCH/MOSAIC in_frm in_tab out_frm method,data [match] [xref,yref] [xoff,yoff] [x_size,y_size] aign and match the elements of the mosaiced frame

SHIFT/MOSAIC out_tab [curs_opt] [csx,csy] [clear_opt] get x and y shifts of subrasters in the mosaiced frame
