Comparison of the integral averaged spectra of the magnetized neutron star models (solid and dashed curves) with black-body spectra, which fit the model spectra at E ≥ 0.5 keV (dotted curves). The differences at the optical band are also shown. Top panel: the models with black-body local spectra and the Gaussian line (τ = 3.0, σ = 30 eV), centered according to Eq. (26), for three temperature distributions: a = 0.25 (upper curves), a = 60 (middle curves), and two-spot model (lower curves). The parameters of the distributions are the same as in Fig. 15. The spectrum of two-spot model with the temperature kT = 0.03 keV of the cold surface is also shown (dashed curve). Bottom panel: the models with smooth temperature distribution (a = 0.25) and various local model spectra: naked iron spectrum (solid curves) and the thin model atmosphere above condensed iron surface spectra (dashed curve). Parameters of the local spectra are the same as in Fig. 13.
