Computes whether the mount is German equatorial (GEM) and if given destination right ascension would cause the mount to end up on the east side of the pier (looking west) if slewed-to.
Util.IsGEMDestinationWest(RightAscension, [Declination])
The method syntax has these parts:
| Part | Description |
|---|---|
| RightAscension (Double) | the destination right ascension (hours) |
| Declination (Double) | the destination declincaiton (degrees, optional default = 0) |
| Return (Boolean) | True if GEM and destination would place mount west of pier |
This is typically used when adding an observation to the pointing corrector at times other than as a result of a slew at the present time. See Util.AddPointingObservation().
Note that as of ACP 7.2, this method has the optional second parameter for Declination.
