NAME

fitsverify - Test if the input file(s) conform to the FITS format

SYNOPSIS

fitsverify filename ...
 
fitsverify @filelist.txt

DESCRIPTION

This task reads one or more input FITS files and verifies that the files conform to the specifications of the FITS Standard document (known as the NASA/Science Office of Standards and Technology 'Definition of the Current FITS Standard', document number, NOST 100-2.0, available online at http://fits.gsfc.nasa.gov/). The input filename template may contain wildcard characters, in which case all matching files will be tested. Alternatively, the name of an ASCII text file containing a list of file names, one per line, may be entered preceded by an '@' character.

OPTIONS

-l
list all header keywords
-q
quiet; print one-line pass/fail summary per file
-e
only test for error conditions; don't issue warnings
-h
