Running from the C-shell

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:

% debias in='"datar*,ffr?"' extent='[51,1094,1,1024]'

If in doubt, it is a good idea to put single quotes around arguments in this way - it can't hurt.
