NAME

       hierarch28 - header conversion from ESO to standard FITS

SYNOPSIS

       hierarch28 [options] <FITS> [table]

DESCRIPTION

       hierarch28  will  convert  keyword  names  in  a  FITS  header  to new names, using a user-provided ASCII
       conversion table. It is especially aimed at removing no-standard FITS features, such as the HIERARCH  ESO
       keyword names.

       hierarch28  can  also  perform a translation to the IRAF convention on the following four keywords: 'RA',
       'DEC', 'UT' and 'LST'. IRAF requires these keywords to contain the string representation of their values,
       e.g.
       RA      = ' 09:45:14.594'
       DEC     = '-33:47:09.420'
       UT      = ' 01:17:21.950'
       LST     = ' 08:19:59.688'

       The  ESO  standard (see http://archive.eso.org/dicb) defines these keywords as floating point values with
       the units degrees for RA/DEC and elapsed seconds since midnight for UT/LST.

       In order to have this translation performed, add
       RA = RA
       DEC = DEC
       UT = UT
       LST = LST
       to the conversion table.

OPTIONS

       -g     This option is used to generate default translation tables.

FILES

       hierarch28 expects a conversion table in input. Default name for this table is table.conv in the  current
       working  directory.  Indicate another name for this file as last argument on the command-line. This ASCII
       file contains a list of keywords to replace, in the following format:

       #
       # Comment lines start with a hash '#'
       # Blank lines would be ignored
       #
       OLDKEYWORD1 = NEWKEYWORD1
       OLDKEYWORD2 = NEWKEYWORD2
       etc.

       Input keywords are character strings, they may contain blanks. Example:

       HIERARCH ESO DET DIT = DETDIT

       One important restriction is that the new keyword name may not  be  longer  than  the  initial  one.  The
       program will complain that it cannot achieve search and replace if this is the case.

IMPORTANT

       This  programs  achieves  maximal  speed to operate because it modifies the input file directly. Be aware
       that using hierarch28 on a file will modify its contents in an irreversible way!
