Dear Michael,
There is nothing to read in Russian - it says "~10 times measure the star-Polaris angle, average to minimise the observation errors, then apply the refraction corrections from Annex#2 (pp.290-291). The obtained value should be compared with the relevant value from the Annex#3 (p.292). Plot all the differences (from all the stars) extrapolated at multiples of 10° for later use".
That's it.
I'm meditating staring at Annex#2 - no avail. How should I use them? Yes, I know my latitude, I know Kochab's altitude. From these I get some value and add it to the value from Annex#3. But what should I do with those mystic columns - the (φ-D) and (φ+D)? The "D" is, I guess, the 16,6° in Kochab's case. I'm stuck completely here...
Please comment.
Warm regards,
Tony
