Surface gravities corrected for centrifugal acceleration (upper panel) and effective temperatures (lower panel) for the stars listed in Table 2, as a function of spectral type. LC I objects are denoted by circles, LC II/III objects by triangles, and LC IV and V objects by open and filled squares, respectively. The calibrations from Martins et al. (2005a) are overplotted: the solid line indicates dwarfs, the dashed line indicates giants, and the dotted line indicates supergiants. Fast rotators are additionally denoted by large circles. For clarity, some objects were shifted slightly horizontally.
