*calc_bary* - Computing Barycentric Corrections

The satellite ephemeris is used to compute arrival time corrections from the satellite to the solar system barycenter, appropriate to an input celestial position. If the ephemeris data file is in Rev. 0 format, it is converted to RDF format.

input files: rp110590_eph.tab (Rev. 0) or rp110590n00_eph.tab (RDF)

output files: rp110590n00_cor.tab, rp110590n00_ephem.tab

  ti> calc_bary
  input ephemeris table : xdata$rp110590_eph.tab                # A Rev. 0 file
  root name for output file(s) [root_cor(ephem).tab] : .
  input RA (hh:mm:ss.s) : 22:08:41.6 
  input DEC (dd:mm:ss.s) : 45:44:47.3

  Converting Rev0 US format EPH file to RDF format ...
  Opening file: xdata$rp110590_eph.tab
  40 rows written to output table.
  Output file: ./rp110590_ephem.tab
  Output ephemeris table: ./rp110590_ephem.tab

Alternatively, for RDF input

  ti> calc_bary
  input ephemeris table: xdata$rp110590n00_eph.tab                # an RDF file
  root name for output file(s) [root_cor(ephem).tab]: .
  input RA (hh:mm:ss.s): 22:08:41.6
  input DEC (dd:mm:ss.s): 45:44:47.3

  RDF input ... No conversion!!
  Output ephemeris table: ./rp110590n00_ephem.tab

  Opening file: ./rp110590n00_ephem.tab
  Output Correction table: ./rp110590n00_cor.tab
