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.

 

Table 3.11: CCD commands

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
