CNLHA - Calculate Local Hour Angle (LHA)
Description: Determine the LHA of a celestial object from its GHA and the observer's DR longitude.
Inputs:
| GHA | GHA of the celestial object |
| Lon | Longitude of the observer |
Outputs:
| LHA | LHA of the celestial object from the observer's meridian |
Sample execution:
GHA? 41,16.2 Lon? -5,06.3 LHA: 36° 09.9'
