Notes. The time spent accumulating photons for each frame (a single frame is here the result of 7 stackedimages) is referred to as the integration time and is the same for all observations: tint = 33.6 s. We note that the image read-out is performed in parallel of the next exposure leading to an effective data cadence equal to the integration time (duty cycle of 100%). (1)Each file key refers to a unique observation in the CHEOPS database. (2)UTC start and end are the starting and ending dates of the observation in UTC. (3)The efficiency represents the ratio between the observation time without interruptions (due to Earth occultation or SAA crossings) and the total observation duration.
