Sample folded light curves comparing the G-band and Hα as a phase function, each light curve is folded on its respective periods. The MBPs for the G-band positions are shown as: a. 459, 632 (MBP #5); b. 670, 640 (MBP #13); c. 708, 846 (MBP #17); and d. 770, 642 (MBP #21). Signals for panel a show a strong anti-correlation. Signals from panel c show a strong correlation, while panels b and c show weaker positive correlations (see the main text).
