    Re: SNO-T lunar accuracy and arc calibration

    Dear Modris,

    I found it. It is the Russian book by V. T. Kondrashykhin and A. N. Rakhovetskii, Accuracy of astronomical determinations of ship's position, 1962. (В. Т. Кондрашихин, А. Н. Раховецкий, Точность астрономических определений места судна. Мосркой транспорт, 1962.)

    It is a small book, only 69 pages. The tables we are discussing are  Appendix 2. This appendix consists of the Main table which gives distances from Polar star to 6 stars. These distances are computed for 1960. And then for each of these 6 stars a table of corrections for refraction. The tables of correction has two entries: the latitide (=height of the Polar star) and height of the other star.

    So these correction tables have permanent value, while the main table is out of date. Since you probably do not read Russian, you don't need the whole book, so I will only copy  the tables and send them on Monday or Tuesday.
