    Sector Notes

    Noted Issue Description
    Spacecraft pointing: The pointing in Sector 87 was set at -55.5 degrees in ecliptic latitude. Camera 4 was pointed near the South Ecliptic Pole. Camera 4 was used for guiding in all four orbit segments (Orbits 181a, b and 182a, b). Camera 1 was also used for guiding in two of the orbit segments: Orbits 181b and 182a.
    Scattered light: In Sector 87, the Earth introduces scattered light signals towards the beginning of each orbit, and the Moon impacts Cameras 1 and 2 at the start of Orbit 181a and end of orbit 182b.
