Gord,
I'm assuming you know how to figure Assumed Lat and Assumed LHA. Given
that,
1. A = arcsine( cos(Lat) * sin(LHA) )
2. Z1 = arcsine( cos(LHA) / cos(A) )
3. B = arcsine( cos(Lat) * sin(Z1) )
4. F = B + Dec
5. F = round(F); F' = fractional part of F
6. A = round(A); A' = fractional part of A
7. H = arcsine( cos(A) * sin(F) )
8. Z2 = arcsine( cos(F) / cos(H) )
9. P = arcsine( cos(A) * sin(Z2) )
10. Corr1 = F' sin(P)
11. Corr2 = A' cos(Z2)
Is this what you are looking for?
Regards,
