Field Location On The Sky
The Kepler photometer consisted of 21 CCD modules (each with two 2200 x 1024 pixel CCDs). Each module covered 5 square degrees on the sky. The full 116 square degree field of view on the sky is illustrated below, specifically for the single field that was observed during the prime Kepler mission. For more information on converting pixel coordinates to sky coordinates, consult Section 7.6 in the Kepler Instrument Handbook.
Machine-Readable Table
A table (morc_2_ra_dec_4_seasons.txt) that contains the corners of each Kepler CCD module is available for download in text format. Corners are provided in J2000 celestial coordinates for all four seasonal roll rotations.
Start and Stop Times For Each Quarter
NOTE: For more detailed start and stop times for the long-cadence and short-cadence runs of each Quarter, consult Table 2 and Table 3 in the DR25 release notes. The table below contains the mid-point times of the first and last cadence of each Quarter.
