TESS Cycle 5 CPD. All the periods shown here have powers above the threshold for this cycle. Prot measurements identified for removal due to source confusion either by GVC objects or by other cluster members are marked with orange crosses. A significant fraction of these Prot are <0.5 days, faster than we would expect for stars earlier than mid-K at this age, for example (see D. J. Fritzewski et al. 2021a).
