Dest (Destination)

The variable array in which the results of the instruction will be written. Dest must be dimensioned to 5 or a compilation error will occur. The following 5 values are returned:

• Dest(1) = SolarAzimuth (degrees from North; N=0, E=90, S=180, W=270)
• Dest(2) = SunElevation (degrees above the horizon; 90 degrees corresponds to solar noon)
• Dest(3) = HourAngle (Radians West from solar noon). Converts local solar time into an angular displacement for the sun's movement across the sky.
• Dest(4) =Declination (Radians North or South). Angle between the equator and the location of the sun.
• Dest(5) = AirMass (air mass coefficient). Ratio of the path length of the current solar position to the path length at solar noon. Calculated via Kasten and Young’s method 1989. If a pressure measurement is possible, a correction will be applied and will refer to the airmass as an absolute airmass. If pressure is not used, airmass may be referred to as a relative airmass.
