Example of ﹩{\chi }_{r}^{2}﹩ map represented as a function of null depth and rms phase error σϕ (﹩{\chi }_{r}^{2}﹩ minimized along the mean phase direction). The region where ﹩{\chi }_{r}^{2}\gt 10﹩ has been set to 10 to emphasize the low ﹩{\chi }_{r}^{2}﹩ region. The position of the best-fit model is represented by the white cross.
