Namespace: ASCOM.Tools.NovasCom
Assembly: ASCOM.AstrometryTools (in ASCOM.AstrometryTools.dll) Version: 3.0.0-rc.1+86c25ce733aebb4d8b1b8a62e84770ea5e972bea

C#

public bool SetFromSiteJD(
	Site site,
	double ujd
)

VB

Public Function SetFromSiteJD ( 
	site As Site,
	ujd As Double
) As Boolean

Parameters

site Site: The Site object from which to initialize
ujd Double: UTC Julian Date

Return Value

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.
