    Jeremy,

    Did a reduction crunch on your latest clutch of backsights. The spread was 1.6' and the average intercept was 1.3' toward (darn good for a dip short from 106 ft.). All intercepts worked out toward.

    Double check the posted Hs for meridional passage which I am guessing is Hs 101* 55.1' instead of 101* 35.1'

    Ex-Meridian UT 3:47:44

    Hs 102*21.6'
    DS -30.8' (for 106ft. HE {at} 2.0NM)
    IE -0.8'
    Ha 101* 50.0'
    180
    78* 10.0'
    ref. -0.2'
    Ho 78* 9.8'
    Ex.Corr. 27.0'
    78* 36.8'
    ZD 11* 23.2'
    dec-18* 41.0' S
    Lat. 7* 17.8' S (1.5' toward)

    (a) = 1.9635(Cos Lat)(Cos Dec)/Sin (D-L) = 9.33

    Ex.Corr. = 9.33(13.17)(13.17)/60 =27.0'
