Name
       fitsort  -  sort  FITS  header  information from a list of
       files

Synopsis
       dfits <FITS files...> | fitsort <FITS keywords...>

Description
       fitsort extract keyword values from a set of FITS  headers
       and outputs it in an ASCII table format, which is compati-
       ble with most data processing software packages. It  shall
       only be used in combination with the dfits utility.

       The  ASCII output is shown in columns. Columns are aligned
       with blank characters and also separated  by  tabulations.
       Blank alignment allows human readers to visualize the out-
       put in a pretty format, tabulations are there for  spread-
       sheet  compatibility. If you want to load out fitsort out-
       put into any spreadsheet, specify  that  fields  shall  be
       separated  by  tabulations  and entries separated by line-
       feeds.

       Examples :
       dfits *.fits | fitsort BITPIX NAXIS NAXIS1 NAXIS2

       The output would look like:
       FILE           BITPIX   NAXIS    NAXIS1   NAXIS2
       file0001.fits  16       2        128      128
       file0002.fits  32       2        512      512
       ...

       ESO specific features in the FITS  header  are  also  sup-
       ported.  To  get  values for 'HIERARCH ESO' keywords, just
       give the complete names within double quotes. e.g.

       dfits *.fits | fitsort "HIERARCH ESO INS LENS"

       Another way of giving HIERARCH ESO keywords is to use  the
       short FITS notation, the above example can be given as:

       dfits *.fits | fitsort INS.LENS

       Example:  to  retrieve  the  DPR keywords from an ESO FITS
       header, you would use:

       dfits *.fits | fitsort DPR.CATG DPR.TYPE DPR.TECH

       This second way of requesting HIERARCH ESO keywords is not
       only shorter to type, it also avoids typing quotes or dou-
       ble-quotes on the command-line, making it easier to script
       with fitsort.

       Notice  that the keywords you give on the command-line are
       case-insensitive.  The above line is equivalent to:

       dfits *.fits | fitsort dpr.catg dpr.type dpr.tech

Options
       None

Files
       Input files to dfits shall all comply  with  FITS  format.
       fitsort also supports HIERARCH ESO FITS format.
