+.IP
+Note that this figure of merit compares measurements within one data set, so it isn't really a "comparison" operation in the sense of "compare_hkl". It is nevertheless included in compare_hkl so that the ratio Rano/Rsplit can be calculated (see below). I+ will be taken to be the mean of the I+ values from both data sets, and likewise for I-.
