  Using the method termed complex asteroseismology, we derive constraints on
model atmospheres, in particular, on the NLTE effects. We fit simultaneously
pulsational frequencies and the corresponding values of the nonadiabatic
complex parameter f for the four \beta Cephei stars: \theta Oph, \nu Eri,
\gamma Peg and 12 Lac. The LTE Kurucz models and the BSTAR2006 NLTE models are
tested.
