Figure 1. Periods of the periodic variables (other than purely eclipsing binaries) as a function of their V' magnitude. Multiple periods of the same object are connected with solid lines. The color of each marker indicates the group to which the star belongs: red for SPB variables, green and cyan for new class variables, blue for delta Sct variables, magenta for gamma Dor variables, and black for either red giants or periodic variables fainter than V' = 15.5 mag, unless clearly belonging to one of the above-mentioned groups. Adapted from Figure 10 of Mowlavi et al. (2013).
