a From Cohen et al. (1999) or Bordé et al. (2002), except $\alpha$ PsA which angular size was measured by Di Folco et al. (2004). bLinear limb darkening coefficients from Claret et al. (1995) or Claret (2000). $^{{\rm c}}$ The projected rotational velocities were taken from the catalogue compiled by Glebocki et al. (2000).
