CCDPACK commands are made available from the C shell using the command:
(note that the % represents the C-shell prompt and shouldn’t be typed).
CCDPACK commands can also be used from the Starlink/ICL and IRAF/CL command languages (IRAF users should consult section §A).
Help is available in two forms; from the command-line and via a hypertext version of this document. Just type:
to get the command-line version, and:
to load the hypertext version. The hypertext version has one optional parameter, the name of the WWW browser to use. The default is the Netscape Navigator although NCSA Mosaic can also be used. If you prefer Mosaic try the command:
If this doesn’t work then replace the word Mosaic with the command that starts the browser for you
(this shouldn’t be an alias). If you want to always use Mosaic then set the environment variable
HTX_BROWSER to Mosaic in your .login file.
Help is also available in the reduction GUI menus or from program prompts (by responding with a ‘?’).
If you come across any bugs or problems when using CCDPACK then e-mail a description to:

When using CCDPACK from the C-shell (or any other UNIX shell) care needs to be taken with some
special characters. Wildcard characters *,?,[a-z],{X,Y,Z}, quoted strings "" and vector braces [ ]
must be protected by using either the escape character \ or by single quotes (wildcard characters must
be protected as these are expanded internally by CCDPACK, rather than by the shell). So for instance
to pass the names of several data frames and the extent of the useful part of a CCD you might use a
command like:
If in doubt, it is a good idea to put single quotes around arguments in this way – it can’t hurt.
