Simultaneously measured line intensities of Ca + K and H, Ha, H/3 and He D 3 are presented and compared with recent model calculations by Heasley and Milkey (1978). The model calculations are compatible with the observations. There is indication that the observed branching of the relation E(Ca \* K
