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

Syntax

C#
public double IraEquinox(
	double JdTdb,
	EquinoxType Equinox,
	Accuracy Accuracy
)
Visual Basic
Public Function IraEquinox ( _
	JdTdb As Double, _
	Equinox As EquinoxType, _
	Accuracy As Accuracy _
) As Double
Visual C++
public:
virtual double IraEquinox(
	double JdTdb, 
	EquinoxType Equinox, 
	Accuracy Accuracy
) sealed

Parameters

JdTdb
Type: System..::..Double
TDB Julian date.
Equinox
Type: ASCOM.Astrometry..::..EquinoxType
Equinox selection flag: mean pr true
Accuracy
Type: ASCOM.Astrometry..::..Accuracy
Selection for accuracy

Return Value

Intermediate right ascension of the equinox, in hours (+ or -). If 'equinox' = 1 (i.e true equinox), then the returned value is the equation of the origins.
