Convert to a new
celestial coordinate system.
The application will convert mean equatorial coordinates to mean equatorial coordinates for another
equinox and epoch, to Galactic coordinates or to de Vaucoulerurs supergalactic coordinates. The new
coordinates may be computed simply from an existing Right Ascension and Declination.
Alternatively, more accurate values may be computed using columns of proper motion and parallax if
these are available in the input catalogue.
A copy of the catalogue containing the new coordinates is created. The new coordinates may either
replace coordinates in existing columns or be written to new columns.
CATIN = CHARACTER (read)
Name of the input catalogue.
CATOUT = CHARACTER (read)
Name of the output catalogue.
EPOCHI = CHARACTER (read)
The epoch of the input coordinates,
eg: J2000 or B1950.
EQUINI = CHARACTER (read)
The equinox of the input coordinates, eg: J2000
or B1950.
RAIN = CHARACTER (read)
The name of the column containing Right Ascension in the
input catalogue.
DECIN = CHARACTER (read)
The name of the column containing Declination in
the input catalogue.
FULL = LOGICAL (read)
A flag indicating whether full input coordinates
(including proper motions and parallax) are to be used or not. It is coded as follows: TRUE -
use full input coordinates, FALSE _ simply use input Right Ascension and Declination.
PMRA = CHARACTER (read)
The name of the column containing the proper motion in
Right Ascension in the input catalogue.
PMDE = CHARACTER (read)
The name of
the column containing the proper motion in Declination in the input catalogue.
PLX =
CHARACTER (read)
The name of the column containing the parallax in the input catalogue.
RV = CHARACTER (read)
The name of the column containing the radial velocity in
the input catalogue.
COORDS = CHARACTER (read)
The type of output coordinates
to be computed. The options are: EQUATORIAL - equatorial coordinates, GALACTIC -
Galactic coordinates, SUPERGALACTIC - de Vaucoulerurs supergalactic coordinates.
EPOCHO = CHARACTER (read)
The epoch of the output coordinates, eg: J2000 or B1950.
EQUINO = CHARACTER (read)
The equinox of the output coordinates, eg: J2000 or B1950.
RAOUT = CHARACTER (read)
The name of the column to contain the Right Ascensions
computed for the new equinox and epoch.
DECOUT = CHARACTER (read)
The name of
the column to contain the Declinations computed for the new equinox and epoch.
L =
CHARACTER (read)
The name of the column to contain the computed Galactic longitude.
B =
CHARACTER (read)
The name of the column to contain the computed Galactic latitude.
SGL =
CHARACTER (read)
The name of the column to contain the computed supergalactic
longitude.
SGB = CHARACTER (read)
The name of the column to contain the computed
supergalactic latitude.
TEXT = CHARACTER (read)
Flag indicating the textual header
information to be copied. The valid responses are: A - all; the output catalogue will contain a
complete copy of the header information for the input catalogue, duplicated as comments, C -
(default) copy only the comments from the input catalogue. In the case of a FITS table
the COMMENTS and HISTORY keywords will be copied. N - none; no textual header
information is copied.
QUIET = LOGICAL (read)
Operate in quiet mode where warnings are
suppressed. The permitted values are: TRUE - quiet mode, FALSE - verbose mode.
