Phase-folded light curves of periodic variable stars identified in the NGC 381 region. The plots are given for twice the phase value for a good presentation. The star IDs, periods (p) in days, and variability types are noted at the top of each light curve. The original light curves and Lomb–Scargle periodograms are shown in Figure 14 in the Appendix. The light curves for the eclipsing binaries are given in Figure 6. The light curves for stars 1602 and 4049 are shown in Figure 12. These two stars are reported to be RS Canum Venaticorum-type (RS CVn) variables in the literature (Watson et al. 2006).
