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.
161834 is double:
Graze prediction is based on the mean position of AB 7.75 9.00 0.40" 153.2
(RST3198) Graze path of A approximately 0.2 km south, and 0.1 secs earlier compared to prediction
Graze path of B approximately 0.6 km north, and 0.2 secs later compared to prediction
