    Re: Russian Tables of Computed Altitude and Azimuth
    From: Tony Oz

    Dear Igor,

    • No, I do not have the BAC-58 at all.
    • Yes, TBA-57 is also presented in the MT-2000 but in less compact form.

    I can understand why they prefer a method allowing to do an SR from any position (D.R. or A.P.) which is possible with the TBA-57 rather than to mess with pre-calculated altitudes and azimuths for selected LHAs and LATs (which essentially is the BAC-58).

    (A note for non-Russian readers: the TBA stands for "Таблицы Высот и Азимутов", i.e. the Tables of Altitudes and Azimuths; the BAC stands for "Высоты и Азимуты Светил", i.e. the Altitudes and Azimuths of Luminaries)

    As I can understand, the BAC-58 is the same as either HO-249 or HO-229, and the TBA is (is it?) similar to HO-214, right?

    Regards,
    Tony
