CPDs for low-mass members of NGC 3532 with TESS light curves for each TESS cycle in which they were observed, before (left) and after (right) our analysis removing erroneous measurements. As in Figure 2, blue circles represent our targets for Prot measurement with TESS; red circles represent stars with a Prot measurement that agrees with that from D. J. Fritzewski et al. (2021a) within 15%. In each CPD, we omit stars for which we measured Prot > 15 days.
