VelocityVectorSetFromSiteJD Method (Site, Double)
Initialize the VelocityVector from a Site object using UTC Julian Date

Namespace: ASCOM.Astrometry.NOVASCOM
Assembly: ASCOM.Astrometry (in ASCOM.Astrometry.dll) Version: 6.0.0.0 (6.2.0.2774)
Syntax
public bool SetFromSiteJD(
	Site site,
	double ujd
)

Parameters

site
Type: ASCOM.Astrometry.NOVASCOMSite
The Site object from which to initialize
ujd
Type: SystemDouble
UTC Julian Date

Return Value

Type: Boolean
True if OK otherwise throws an exception
Remarks
The velocity vector is that of the observer with respect to the Earth's center of mass. The Julian date must be UTC Julian date, not terrestrial. This call will use the internal tables and estimator to get delta-T. This overload is not available through COM, please use "SetFromSiteJD(ByVal site As Site, ByVal ujd As Double, ByVal delta_t As Double)" with delta_t set to 0.0 to achieve this effect.
