Name¶
gethead - Print FITS or IRAF header keyword values
Synopsis¶
gethead [-hptv] [-d pathname] [-n num] <FITS or IRAF file> kw1 kw2 ... kwn
Description¶
Print values of the specified keywords from the given image header. By default
they are all listed on one line, separated by spaces. The
-v flag
causes the keyword names and values to be printed, one keyword per line. To
read keywords from a list of files, substitute @<listfile> for the file
names on the command line. To read a lot of keywords, put them, one per line,
in a file and substitute @<keylistfile> on the command line. If two @
commands are present, the program will figure out which contains file names
and which contains keywords.
