Be careful when you compare the plots.<br /><br />There are a few trends from our Fig 9.:<br /><br />1) For planets with R < ~3 R_Earth, dN/dlogR is consistent with being flat for P > 10 days (red and green).<br /><br />2) For planets with R >~3 R_Earth and R <~ 10 R_Earth with 10 days < P < 50 days, dN/dlogR decreases as R increases (red).
