    Sector Notes

    Noted Issue Description
    Spacecraft pointing: The pointing in Sector 86 was set at +55.5 degrees in ecliptic latitude. Camera 4 was pointed at the North Ecliptic Pole. Cameras 1 and 4 were used for guiding in Orbits 179b and 180b. Camera 4 was used for guiding in Orbits 179a and 180a. Pointing at the end of the first half orbit (179a) was highly variable, as seen in the delta-quaternion scatter in Figure 1 from TJDs 3641 – 3642.75. During this time, pointing excursions frequently exceeded the 7” threshold adopted by the PDC, TPS, and DV modules, resulting in exclusion of ∼2/3 of the cadences.
    Scattered light: In Sector 86, the Earth introduces scattered light signals towards the beginning of each orbit, and the Moon impacts Cameras 1, 2, and 3 near the middle of Orbit 180b.
