Notes. The table lists the time interval of individual observations (time notation follows the ISO-8601 convention), the file key, which supports fast identification of the observations in the CHEOPS archive, the efficiency, which is the ratio between the amount of science observing time available during a visit and the total amount of time in a visit, the point-to-point root mean square (RMS) of the DRP-processed light curves with an aperture radius of 24 pixels, and the number of obtained frames.
