Initialize the VelocityVector from a Site object using UTC Julian Date and Delta-T

Namespace: ASCOM.Astrometry.NOVASCOM
Assembly: ASCOM.Astrometry (in ASCOM.Astrometry.dll) Version: 6.0.0.0 (6.1.1.2619)

Syntax

C#
public bool SetFromSiteJD(
	Site site,
	double ujd,
	double delta_t
)
Visual Basic
Public Function SetFromSiteJD ( _
	site As Site, _
	ujd As Double, _
	delta_t As Double _
) As Boolean
Visual C++
public:
virtual bool SetFromSiteJD(
	Site^ site, 
	double ujd, 
	double delta_t
) sealed

Parameters

site
Type: ASCOM.Astrometry.NOVASCOM..::..Site
The Site object from which to initialize
ujd
Type: System..::..Double
UTC Julian Date
delta_t
Type: System..::..Double
The optional value of Delta-T (TT - UT1) to use for reductions (seconds)

Return Value

True if OK otherwise throws an exception

Implements

IVelocityVector..::..SetFromSiteJD(Site, Double, Double)

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.
