Table 2. Complexity calculations for some selected RP phases with a focus on series based on SrTiO3 and RbCdCl3 .
I G values shown in italics were not used in the regression which is mentioned in the text, since RbCdCl3 does not crystallize in a perovskite structure and the anion-deficient compounds are only close to the RP information content.
