Detailed Description
The NeedsRefractionInterface for mounts.
Mounts that need refraction adjustments means coordinates returned by a mount are tainted by refraction and the control system does not do its own internal refraction adjustments. For example, the Paramount and the Bisque TCS, return true from this interface so TheSkyX can act accordingly.
If a mount does its own, internal,refraction, this means the coordinates returned from a mount have the effects of refraction removed. An example of such a mount is the Meade LX200.
What this means under the hood, if an X2 mount object returns true to needsRefactionAdjustments() 1)Upon reading raDec, TheSkyX removes the effects of refraction so the "real" object's location is lower than where the mount is currently, physically pointing to in altitude through the atmosphere. 2)Before syncing a mount to a cataloged coordinate, (setting raDec) TheSkyX adds in the effects of refraction to the cataloged coordinate. This is opposite of #1 - in other words, on sync, intitialize the control system so that when we read raDec and subsequently remove the effects of refraction, the coordinates are the "real" topocententric coordinates.
Definintion - refraction is zero at zenith, max positive at horizon (a positive value)
