The top panel shows the distribution of  for our full sample of stars. Most stars are located around the inactive part of the distribution (≤  −4.8). We note there is a lack of stars around the Vaughan Preston gap and then a slight indication of the expected secondary active bump in this bimodal distribution. We overplot the best fit bimodal function by the dashed curve and highlight the reduced χ² of 2.08 we find. The lower panel shows the sample split by main sequence stars (black) and subgiants (green). The subgiants occupy a more inactive state than the main sequence stars.
