StarSetHipparcos Method
Initialise all star properties in one call using Hipparcos data. Transforms to FK5 standard used by NOVAS.

Namespace: ASCOM.Astrometry.NOVASCOM
Assembly: ASCOM.Astrometry (in ASCOM.Astrometry.dll) Version: 6.0.0.0 (6.3.0.2839)
Syntax
public void SetHipparcos(
	double RA,
	double Dec,
	double ProMoRA,
	double ProMoDec,
	double Parallax,
	double RadVel
)

Parameters

RA
Type: SystemDouble
Catalog mean right ascension (hours)
Dec
Type: SystemDouble
Catalog mean declination (degrees)
ProMoRA
Type: SystemDouble
Catalog mean J2000 proper motion in right ascension (sec/century)
ProMoDec
Type: SystemDouble
Catalog mean J2000 proper motion in declination (arcsec/century)
Parallax
Type: SystemDouble
Catalog mean J2000 parallax (arcsec)
RadVel
Type: SystemDouble
Catalog mean J2000 radial velocity (km/sec)
Remarks
Assumes positions are Hipparcos standard and transforms to FK5 standard used by NOVAS.

If Parallax is set to zero, NOVAS-COM assumes the object is on the "celestial sphere", which has a distance of 10 megaparsecs.
