 public static double Dopset(char SynthRestFrame,
                             double Ra,
                             double Dec,
                             double IAT,
                             double Ha,
                             double Lat,
                             double Alt)
Computes Doppler correction. Calculates the magnitude of the velocty of the observer with respect to a given coordinate system.

Parameters:
char - Rest Frame code T=Topocentric, L=LSR, B=Barycentric, G=Geocentric (theScan.Frequency.SynthRestFrame.Value)
double - apparent right Ascension (radians) (theScan.Pattern.BeginObservation.Ra)
double - apparent declination (radians) (theScan.Pattern.BeginObservation.Dec)
double - the IAT time (seconds?) (theScan.Pattern.BeginObservation.IAT)
double - apparent hour angle of source (radians) (theScan.Pattern.BeginObservation.Ha)
double - Observatory Latitude (radians) (Obs.myTelescope.Instrument.Latitude)
double - Observatory Altitude (m?) (Obs.myTelescope.Instrument.Altitude)
Returns:
double Doppler velocity (km/s), 1.0e10 implies some error (theScan.RestFrameVelocity.Value)
