    A-10 Sextant with 31.5' index error off the arc (horizon reading is lees
    than zero in case if am mixed up)
    Sextant has no other calibration. I frequently get LOP's within 2 miles
    of my AP so I am happy. It has backlash so I try not to change
    directions.  I suspect some other error as stars with higher altitudes
    tend to give me bigger errors.
    I am actually quite surprised that I am getting a fix that is close
    enough to find the airport (or Bermuda) if I had do. I have an A-12 and
    Mark IX, but I only drag out one an evening.
    I am presently using CelestNav 3.0 for the palm pilot to work out the
    sites. I would appreciate any comments on the program. I like it for
    everything but the fix calculation, but I think 3.0 is only a Beta.
