| Parameter | Mand | Type | Default | Constraints |
| srclist | no | string | | name of soruce list file |
RGS source list file, needed to extract the source corrdinates
|
| spectrumset | no | string | | name of RGS spectrum file |
spectrum file where the Heliocentric velocity value will be written as a keyword.
|
| srcra/srcdec | no | string | | source coordinates |
If toscreen is set to true the coordinates of the celestial
source have to be specified through these parameters in the
equatorial, earth-centered J2000 reference frame. Recognized formats
are for srcra (Right Ascension)
- 123.45678 (decimal degrees)
and for srcdec (Declination)
- 123.45678 (decimal degrees)

| time | no | real | | |
A single time on which to perform the barycentric correction.
Only used if toscreen is enabled.
|
| ephemeris | no | string | DE200 | DE200|DE405 |
Name of an ASCII earth ephemeris file extension in the JPL format to be used
in lieu of a standard one. This file contains barycentric vectors
needed by the TDB conversion algorithm.
