    Re: SNO-T lunar accuracy and arc calibration

    Dear Alex,

    You wrote: “Another interesting part (at least for me) is some statistical data on SNO-M and SNO-T performance. The book was written at the time when they started replacing SNOM by SNO-T.”

    I have a pdf file of the book: Б .И .К р а с а в ц е в . И н с т р у м е н т ы  и  м е т о д ы  м о р е х о д н о й  а с т р о н о м и и (1972) , where some aspects of accuracy are discussed. But it seems that you meant another book. Can you provide more info (author and name of the book; is it digitalised or paper version; how many pages are devoted to SNO performance). I am greatly interested in these data, because I am an owner of both SNO-T and SNO-M sextants.

    Modris
