PCA results in the Crater II field, including an asteroid (419993/2011CW32). We plot the sources with PC1 quantile larger than 0.5 and combine the results of 18 exposures (visit 632364 to 632398 on CCD 21, 3 minutes exposures in the g band each). The corresponding MJD range is from 57832.232–57832.314, and the teff range is from 0.08–0.22. We annotate the variables (A. K. Vivas et al. 2020) and mark the asteroid (moving from SE to NW). The marker opacity is proportional to the sum of PC1 quantile of each source in individual exposures. V6 and V61 have relatively low brightness during the observation window.
