FITSHEAD

Lists the headers of FITS files

Description:

This procedure lists to standard output the headers of the primary header and data unit, and any extensions present that are contained within a set of input FITS  files, or a range of specified files on a tape.

Usage:

fitshead file [block] [start] [finish]

Parameters:

BLOCK = _INTEGER (Read)
The FITS blocking factor of the tape to list. This is the tape blocksize in bytes divided by the FITS record length of 2880 bytes. BLOCK must be a positive integer, between 1 and 12, otherwise you will be prompted for a new value. Should the first argument not be a tape device, this argument will be treated as a file name. [1]
FILE = FILENAME (Read)
A space-separated list of FITS files whose headers are to be listed, or the name of a single no-rewind tape device. The list of files can include wildcard characters.
FINISH = _INTEGER (Read)
The last file on the tape to list. This defaults to the end of the tape. It must be a positive integer and at least equal to the value of start, otherwise you will be prompted for a new value. Should the first argument not be a tape device, this argument will be treated as a file name. []
START = _INTEGER (Read)
The first file on the tape to list. This defaults to 1, i.e. the start of the tape. It must be a positive integer, otherwise you will be prompted for a new value. Should the first argument not be a tape device, this argument will be treated as a file name. [1]

Examples:

fitshead /dev/nrmt1
This lists the FITS headers for all the files of the tape mounted on device /dev/nrmt1. The tape block size is 2880 bytes.
fitshead /dev/nrmt1 10 > tape.lis
This lists to file tape.lis the FITS headers for all the files of the tape mounted on device /dev/nrmt1. The tape blocking factor is 10, the tape’s blocksize is 28800 bytes.
fitshead /dev/rmt/0n 2 3 5 > > tape.lis
This appends the FITS headers for files 3 to 5 of the tape mounted on device /dev/rmt/0n to the file tape.lis. The tape blocking factor is 2, i.e. the tape’s blocksize is 5760 bytes.
fitshead /dev/nrst2 prompt
This lists the FITS headers for files of the tape mounted on device /dev/nrst2. The command prompts you for the file limits and tape blocking factor.
fitshead ∼/fits/∗.fit ∼/data/p?.fi∗ | lpr
This prints the FITS headers in the files ∼/fits/∗.fit and ∼/data/p?.fi∗.
