       fitsort - sort FITS header information from a list of files


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


       fitsort  extract  keyword values from a set of FITS headers and outputs
       it in an ASCII  table  format,  which  is  compatible  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 output in a pretty  format,  tabulations
       are  there  for  spreadsheet  compatibility.  If  you  want to load out
       fitsort output into any  spreadsheet,  specify  that  fields  shall  be
       separated by tabulations and entries separated by linefeeds.

       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 supported. 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 To be completed...  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 double-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


       -d     Do not print out the first output line. This option is useful to
              get  only  the  query  results, without the top line (giving all
              column names).  This  makes  it  easy  to  script  fitsort  from
              programs like awk or perl.


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