Notes. Here “diameter” represents the planet diameter as viewed from L2 averaged over all observations, while “sample density” refers to the average sample density, accounting for flagging, within a 40′ wide field of view centred on the planet. The S/N given is the ratio between a fit to the peak signal registering in the timeline and the root mean square (rms) noise.
