Notes. The column “Exposure” lists the effective unvignetted exposure time of each observation, referring to the sum of all good time intervals, corrected for the dead time fraction of the specific detector. The columns “RA” and “Dec” specify the right ascension and declination of the telescope pointing, given in decimal degrees, respectively. The column “Roll” describes the telescope roll angle west of north, given in degrees.
