hierarch28

hierarch28(1)						      General Commands Manual						     hierarch28(1)

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!
