Dear Paul,
You made a notice here:
If (altitude < 0) or (X < 90), replace Z with its supplement:
Z = 180 - Z
Do the adjustment only when EXACTLY ONE of the conditions is true.
Could you please give an example when both conditions are true and the Z must not be altered. (this is how I understand your warning)
By the way, how does your implementation work with the "folded" scales by Gary LaPook?
Thank you in advance.
Warm regards,
Tony
