    Took me a moment to realize that the U.S. flag was the link:
    
    http://niipp-moskva.ru/ppt/booklet_IPIE_int.ppt
    
    Impressive images, especially given the range. Lacrosse 2's radar dish is
    clearly visible.

    I find that the "yM" values match the maximum elevation of the pass.
    
    I found the coordinates of the Altay optical/laser ranging centre (5120' N,
    8210' E) here:
    
    http://cddis.nasa.gov/lw14/docs/papers/upg14_mbm.pdf
    
    Below is an ephemeris of the pass on which Lacrosse 2 was imaged, using
    near-contemporaneous hobbyist elements:
