Surface gravity versus Teff distribution for ZZ Ceti (circles, red) and photometrically constant (squares, blue) DA white dwarfs in the Gianninas et al. (2011) sample with ⟨3D⟩ (top) and 1D (bottom) spectra. The dotted lines are the ZZ Ceti instability strip boundaries established by Gianninas et al. (2006) while the dashed lines are the most recent boundaries identified by Gianninas et al. (2011) relying on the models from Tremblay & Bergeron (2009). The error bars represent the average uncertainties of the spectroscopic method in the region of the ZZ Ceti instability strip.
