I am baffled. Additional comments welcome.
One mistake you are making is subtracting out the index correction. Since
you are joining opposite limbs of the sun, it is the total distance that you are
concerned about. For example, if you had a really terrible index correction
of -1 degree you would have both limb sightings on the arc. For determining
semi-diameter this would not matter as it is the total difference divided by
four. Applying the index correction when you are trying to figure out the
semi-diameter not proper. For normal sights it is of course necessary.
