Path coordinates are referred to WGS84 (as used by GPS), with the
nominal site altitude being referenced to Mean Sea Level. The path
is adjusted for the effects of refraction at low moon altitudes.
Projected diameter of star 7 meters [CHARM/CADARS, 8 measures]
1158 is variable:
1158 = NSV 3671, 5.05, range 0.08, V
