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.
2968 is multiple:
Graze prediction is based on the mean position of Ba,Bb 6.16 9.14 0.48" 61.5
(BAR 12) Graze path of Ba 0.02 km north, and 0.1 secs earlier compared to prediction
Graze path of Bb 0.34 km south, and 0.8 secs later compared to prediction
Ba,Bb 6.16 9.14 0.48" 61.5 (BAR 12) Graze path of Bb 0.36 km south, and 0.8 secs later compared to Ba
Ba,Bb 6.16 9.14 0.50" 58.7 (BAR 12) Graze path of Bb 0.43 km south, and 0.9 secs later compared to Ba
BA 6.1 3.2 205" 87.0 (STFA 52) Graze path of A 26.92 km north, and 392.5 secs later compared to B
