Notes. Comparison between synthetic and observed Hα amplitudes (first part) and comparison of the observed and synthetic Hα/Ca ratio, for the different hypothesis for plage emission in Hα (A, B, or C). The values indicate the median of each ratio over all considered stars. Categories are defined in Sect. 4.1.1. When all stars are concerned (last column), they correspond to 152 stars for LT values and 320 stars for ST values.
