Notes. The satellite longitude (positive values: east, negative values: west), latitude (positive values: north, negative values: south), and altitude values (in kilometers above the Earth’s surface) are needed to calculate the correct viewing geometry for the Moon (distance, phase angle, and apparent diameter). (a) Moon was only fully included in the FOV in ch18 and ch19. (b)Possibly touching edge of ch08-ch12FOV. (c)Possibly touching edge of ch08–ch19 FOV. (d)Possibly touching edge of ch01–ch19 FOV. (e)Moon was only in ch18 and ch19 in the FOV.
