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.
