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
