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 @ 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'
