I have not yet plunged into the math details of TBA-57 but these are currently part of MT-2000 nautical tables (one can actually download it for free).
I've heard that soviet seamen preferred it more than the other sight reduction tables namely ВАС-58 which are 4 volumes of latitude range of 20°.
P.S.: Do you have by any chance BAC-58 in pdf? I could not find it.
