V′ magnitudes from Paper I compared to Johnson V band magnitudes from Moitinho et al. (1997), the latter labeled V_Moitinho in the figure. Red indicators identify SPB candidates, and green indicators, new variability class candidates. The vertical lengths of the indicators equal the uncertainties in V′, taken to be the largest value between the V′ error bar from Paper I and the standard deviation of V′ light curve. The horizontal lengths equal the uncertainties in V_Moitinho taken from Table 3 of Moitinho et al. (1997). A weighted fit to the data, excluding stars 21 and 30 because they show bursts in their light curves, leads to V′ = (1.000 ± 0.004)V_Moitinho + (0.031 ± 0.041) mag. The fit, converted to the relative deviation of V′ with respect to V_Moitinho, is shown with the dashed line in the figure.
