    Dave,
    
    There is no point on the celestial sphere that would satisfy the
    condition that its distances from the three stars Altair, Antares and
    Vega match the ones posted in your refraction-free problem to arc second
    level. If, on the other hand, one should compute for extra credit a
    point from the given distances of two of the three stars,  the computed
    distance to the third star differs by ca. 5" to 8" from the remaining
    given one. (Star positions taken from MICA for the epoch of the posted
    solution.)
