Comparison of our method with Mann et al. (2015). The top panel is the result for 5000–8000 Å, and bottom is for 6600–7500 Å. The green lines in the figure represent linear functions fitted to the data. The red points represent stars which have interferometric observations (Lane et al. 2001; Ségransan et al. 2003; Berger et al. 2006; Kervella et al. 2008; Demory et al. 2009; von Braun et al. 2011, 2012, 2014; Boyajian et al. 2012).
