i was going through some of my old sights to familiarize myself with "Weems Line Of Position Book" and found that it ground to abrupt halt, some of my sights (20-25%) are taken above 65°N and reducing them with the LOP book I have is not possible, uhm ok, i could reduce them with minimal error up to 67° and just get longer intercepts but....
OK, it COULD be done accurately if I use table B to solve the PZX-triangle, this as "Table B" is a secant/cosecant table, but the speed advantage would be lost in all but the Azimuth step (muttering).
Anyone have the extra "A" tables published for latitude data between 65° and 90°?
if so could you scan and mail them to me?
