WRITE_IPAC_TABLE

WRITE_IPAC_TABLE

Name


  WRITE_IPAC_TABLE

Purpose


  Write an IPAC table from an IDL structure.

Explanation


  Writes an IPAC table to a file from an IDL structure. If the
  structure has certain pre-defined tag names (see below), the
  header information will be written to the table.

Calling Sequence


  write_ipac_table, in_struct, outfile, [/short_format, /exact_format, format=format]

Inputs


  IN_STRUCT -- an IDL structure containing the table to be written to the output
          ascii file. Header information must be in the keywords, HEADER_TABLE_HEADER,
          HEADER_DATA_UNITS, and HEADER_NULL_VALUES.
  OUTFILE -- string containing the name of the output file

Optional Input


  /SHORT_FORMAT -- if set, uses IDL "print" formats.
  /EXACT_FORMAT -- if set, floating point and double precision
                    data are written with formats of (e16.9) and
                    (e24.17), respectively. This option takes
                    precedence over the /SHORT_FORMAT option.
  FORMAT -- A user supplied format statement that will
                    override the other formating options. This
                    is given in the usual IDL form, e.g. '(f13.6)'.
   

Outputs


    On completion, an ascii table will be written to the outfile.

Procedures Used


    GET_DATE

Notes


    The default format is IDL's '(f)', ('d'), etc.
    The procedure will write out header lines (lines starting with "\"), data unit and null
    value lines if the structure has tag names "HEADER_TABLE_HEADER",
    "HEADER_DATA_UNITS" and "HEADER_NULL_VALUES"
    respectively. If "HEADER_COL_NAMES_ORIG" and
    "HEADER_COL_TYPES_ORIG" are present, these will
    be the column names and types. Currently forces "RA" and "DEC" to lower case.

Modification History

      Output original column names/types if present - T. Brooke, IPAC June 2013
