HR diagram of the studied stars. Evolutionary tracks are from Georgy et al. (2013) for Ω/Ω_c = 0.0 (blue) and for rotation rates at the ZAMS Ω/Ω_c = 0.95 (red). Blue points: stars with their apparent parameters; red points: Stars with their pnrc parameters obtained for Ω/Ω_c = 0.95. Instability strips of β Ceph- (-) and SPB-type (-) pulsators adapted from Walczak et al. (2015) for OPLIB opacities and metallicity of Z = 0.015.
