Dear Michael,
Indeed the stars are carefuly selected to cover all the usable range of angles (not counting lunars). Alas, only for us, northerners.
Because it is easy to keep Annex#3 updated - I think it is very interesting to understand the Annex#2 idea. After all - it is easier (and cheaper) than calibrating a sextant in a lab. The article advertises the precision (of calibrations obtained) to be within ±0,2'.
Regards,
Tony
