Name of IRAF image header file or FITS file from which to extract
header values.
filename
Name of IRAF image header file or FITS file. At least one of these
must be present for any values to be set. File names must have the
extension .imh for either version 1 or version 2 IRAF files
or be legal FITS files.
@listfile
Name of a file listing image file names (IRAF image header files
and/or FITS files) or keyword names. If the first line of the list file
is a FITS or IRAF image file, the list file is assumed to contain image file
names, and any other file names on the command line will be ignored. If
the first line is not an image file, this list file is assumed to contain
keyword names, one per line. No more than two list files, one of images
and one of keywords to be assigned, are allowed on a single cphead
command line. Note that values from all keywords in a file are
transferred to all of the images which are processed, whether they
come from the command line or from a list file.
keyword
Name(s) of keyword(s) whose value(s) are to be transferred from the
header of the template file to the other image files. Names may be
entered in either upper or lower case; they will be automatically
translated to upper case by the program. All command line arguments
which do not start with - and are not image files are assumed to be keywords.
