The method syntax has these parts:
Part |
Description |
SiderealTime (Double) |
sidereal time, hours |
RightAscension (Double) |
right ascension, hours |
Return (Double) |
hour angle, degrees positive-east -180 to 180 |
Remarks
DEPRECATED Use Util.HourAngle12() for all new scripts. For this function, hour angle is right ascension - sidereal time, converted to degrees.
The hour angle returned from this function is backwards. Positive hour angles are to the east, rather than the conventional positive-west. This is not going to change; we don't want to break existing scripts.
