C#

public void SetHipparcos(
	double RA,
	double Dec,
	double ProMoRA,
	double ProMoDec,
	double Parallax,
	double RadVel
)

VB

Public Sub SetHipparcos ( 
	RA As Double,
	Dec As Double,
	ProMoRA As Double,
	ProMoDec As Double,
	Parallax As Double,
	RadVel As Double
)

Parameters

RA Double: Catalog mean right ascension (hours)
Dec Double: Catalog mean declination (degrees)
ProMoRA Double: Catalog mean J2000 proper motion in right ascension (sec/century)
ProMoDec Double: Catalog mean J2000 proper motion in declination (arcsec/century)
Parallax Double: Catalog mean J2000 parallax (arcsec)
RadVel Double: 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 mega parsecs.
