Notes. Each of the five epochs of observation is assigned an identifier (ID) used throughout this work. The table lists the epoch of observation, filter band, detector integration time (DIT) for a single exposure, number of exposures co-added per stored frame, number of usable frames, total integration time, full width of the field of view (FoV), range of parallactic angles covered, whether or not the target star was saturated in the science images (sat.), the number of PSF reference stars, and the publication describing the data in detail.
