GetAzimuthAngleT gets the topocentric azimuth angle (westward from south) 0-360 degrees.
GetElevationAngleT gets the topocentric elevation angle
GetDeclinationT gets the topocentric sun declination
GetHourAngleT gets the topocentric local hour angle
GetRightAscensionT get the topocentric sun right ascension
GetZenithAngleT gets the topocentric zenith angle

"Topocentric" means that the angle is calculated with respect to the observer local position at the earth surface.

SolarPlexus.SetInput must be called in advance to set the input values for date, place on earth etc.

Syntax

DecDegrees = SolarPlexus.<GetAngleT>(Degrees)

<GetAngleT> is one of the above mentioned properties

 

DecDegrees Return value. Double. Angle returned as decimal numeral with degrees before the decimal point, and decimal fractions af degrees after. Example: 117.343242
Degrees Return value. String. Angle returned as a string with the format "pggg:mm:ss.ff", where p=sign (+ or -), ggg=degrees, mm=minutes, ss=seconds, and ff=fractions of seconds. Example: "-117:20:35.67" (which equals -117.343242)
