Notes. The values are given for a single camera and for 24 cameras, and were extracted from Marchiori et al. (2019). The rightmost column gives the photon noise limit, that is the NSR one would have if we were limited only by the photon noise of the target. Values in boldface represent the performance in terms of NSR to be archived with stars observed by all the 24 cameras. Values given for a single camera should not be used as a reference for the mission performance.
