Notes :-
Input Trinidad & Tobago Local Time.
Vertical Readings are complementary to Altitude i.e. Zenith = 0
; Horizontal = 90

The Tobago CM is used automatically when φ > 11 05' N for Cassini.
The [Clear All] Button clears the worksheet and inserts the Current Date & Local Time.
The [New Set] Button clears the Sun Observations and Azimuths for a new set.

The Central Meridian
λo for Cassini Trinidad = 61 20' 00" W
