v sini vs. P_rot (top panel) and pEW(Hα) vs. P_rot (bottom panel) for stars with new (blue filled circles) and re-computed rotation periods in this study (blue open circles) and stars in Carmencita with previously published rotation periods (red dots). In the top panel, the dotted lines indicate the lower and upper envelopes of the v sini − P_rot relation, and most of the values at v sini = 2 or 3 km s⁻¹ are upper limits. Compare with Figs. 6 and 8 in Jeffers et al. (2018). Here we present 154 new or improved v sini − P_rot and pEW(Hα)–P_rot pairs, with periods from this work and velocities and Hα equivalent widths from Reiners et al. (2018b). Outlier stars in both panels are discussed in the text.
