dfits

dfits(1)						      General Commands Manual							  dfits(1)

NAME

       dfits - display FITS file header information

SYNOPSIS

       dfits [-x xtnum] <list>
       dfits [-x xtnum] -

DESCRIPTION

       dfits  displays FITS header informations on stdout. Header information can be found in the main header only (default), in extensions, or in
       both.  See the -x option below.	dfits accepts multi-file input.  'dfits -' expects single file data coming from stdin.	dfits also accepts
       now 'HDR' files. These are identified from the fact that they contain a line feed in one of the 80 first characters.

OPTIONS

       -x xtnum
	      Specifies the extension to print out. Extensions are numbered starting from 1. If this option is not specified, only the main header
	      is printed out. If this option specifies an extension that does not exist, nothing is printed out.
	      Specify 0 as extension number to get a print of the main header plus all extension headers.

       Examples :
       dfits *.fits
       dfits *.fits | grep NAXIS3
       gzip -d < star.fits.gz | dfits - | more
       dfits -x 0 *.fits
       dfits -x 3 *.fits

SEE ALSO

       fitsort can be combined with dfits output to sort out keyword values of a group of FITS files.

FILES

       Files shall all comply with FITS format
