NAME

fitsverify - test if file conform to the FITS format

SYNOPSIS

fitsverify [OPTION]... FILE...
fitsverify [OPTION]... @FILELIST

DESCRIPTION

fitsverify is a utility program designed to verify that 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 https://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

Flags must be separate and appear before filenames.

Test ESO HIERARCH keywords
List all header keywords.
Quiet, print one-line pass/fail summary per file.
Only test for error conditions, don't issue warnings.
Show help.
