    Sector Notes

    Noted Issue Description
    Spacecraft pointing Sector 51 consists of observations of the northern ecliptic hemisphere, with Camera 4 pointed near the north ecliptic pole. Camera 4 alone was used for guiding in both orbit 109 and orbit 110.
    Scattered light The Earth is above the sunshade for extended periods of time in Sector 51, which results in high background levels and large gaps in the light curves. At the start of orbit 109 and orbit 110, the Earth crosses through Cameras 1 and 2, saturating the CCD detectors and/or causing strong glints. Throughout orbit 110, the Moon moves through Camera 1, saturating the detectors and causing strong glints and scattered light signals in both Cameras 1 and 2.
