Position of the pulsating stars in the Kiel (top) and HRD (bottom) diagram. The different types of pulsators are indicated with various symbols: rapid pulsators sdBV_r (open red circles), slow pulsators sdBV_s (open blue circles), and hybrid pulsators sdBV_rs (green filled circles). Stars found to be constant are indicated with grey filled circles. Feige 46 and LSIV-14°116 (blue open squares) are peculiar slow pulsators belonging to the small class of iHe-sdOBV (V366 Aqr). The ZAEHB (dashed line) is indicated for a core mass of 0.47 M_⊙ and corresponding evolutionary sequences of the core-helium burning phase are shown for different H-envelope masses (dotted lines). Stars with a poor parallax measurement are excluded in the bottom panel. Representative errors are shown in each panel.
