Model spectra with the observed fdcut continua for observations I and II. (I): = 5 × 1016 g s-1, the polar cap radius r0 = 0.38 km, the height of the column z0 = 77 m, ne = 2.66 × 1021 cm-3. (II): = 1.5 × 1016 g s-1, r0 = 0.32 km, z0 = 180 m, electron density ne = 1.12 × 1021 cm-3. The temperature of the scattering electrons is Te = 5 keV in both cases.
