Time-series of 
, log IHα, and correlation between the two for the 12 stars with “strong” correlations. Grey dots are nightly averaged data, black points are binned data. Error bars are the standard errors on the mean. Black lines are best fit to the binned data. A sinusoid will appear in the time-series if well fitted, i.e., having p(F) ≤ 0.05.
