Note (1):
* Events during ingress:
0 = First contact with Moon's limb
1 = First contact with a crater, mare, or other surface feature
2 = Middle of the feature or a bright spot
3 = Second contact with the feature
4 = Second contact with Moon's limb
* Events during egress:
5 = Third contact with Moon's limb
6 = Third contact with a crater, mare, or other surface feature
7 = Middle of the feature or a bright spot
8 = Fourth contact with the feature
9 = Fourth contact with Moon's limb
Note (2):
" " = event occurred in the specified UT day
p = event occurred in the preceding UT day
f = event occurred in the following UT day
