Comparison of the MPS2 fixed-CLV fit diameter, ﹩{\theta }_{{\rm{CLV}}}^{{\rm{MPS2}}}﹩, with θPL and with ﹩{\theta }_{{\rm{CLV}}}^{g}﹩ from Stagger, Kurucz, and MPS1. The upper panel shows the one-to-one comparison; the lower panel shows fractional residuals relative to MPS2. Fixed-CLV fit diameters from different grids agree closely, while θPL shows larger target-to-target scatter relative to MPS2.
