Sector 26



× Warning for Sector 26: The TESS spacecraft configuration file was updated from version ‘0187’ to ‘0188’ between orbit 59 and 60. This update results in different naming convention between the FFIs for the two orbits.

Sector 26 Information

For full data release notes see: DRN37

For a list of TIC IDs with noted issues, see this list.

Update: The TESS spacecraft configuration file was updated from version ‘0187’ to ‘0188’ between orbit 59 and 60. The SPOC data products include this 4 digit identification code near the end of the filename. Therefore the FFIs from orbit 59 have a different 4 digit identification number than those from orbit 60.

    Sector Notes

    Noted Issue Description
    Spacecraft pointing

    The pointing in Sector 26 was set at +85 degrees in ecliptic latitude so that Camera 2 and Camera 3 straddle the ecliptic pole.

    Camera 1 suffered from strong scattered light signals at the midpoint of orbit 59 and orbit 60, and so Camera 4 alone was used for guiding during this sector.
    Scattered light In Sector 26, the Earth is a significant source of scattered light throughout both orbits.
