Sight Reduction and Precomputation |

Computes Altitude (Hc) and Azimuth Angle (Z) given Local hour angle (LHA), Latitude (Lat), and Declination (Dec). To get true Azimuth (Zn) apply standard rules: N. Lat: LHA >180, Zn = Z and LHA <180, Zn = 360 - Z S. Lat: LHA >180, Zn = 180 - Z and LHA <180, Zn = 180 + Z |
