Halpha Activity-Rotation fit (PDF samples)
Posterior PDF samples from the activity-rotation (L-halpha/L-bol vs. Rossby number) fit in Douglas et al. (2014). The model parameters are 1) the constant saturation level, 2) the turnover Rossby number where activity switches from saturated to unsaturated, and 3) the power-law index (beta) for unsaturated activity.
