Fig. 3
Variations in the Hα emission flux over the rotation period (open circles), relative to the variation in the R-band light curve (filled circles). The internal errors in the Hα emission flux measurements are smaller than the symbol size, but gross variations in the flux from cycle to cycle are expected.
