Notes. The fits with the atmosphere models are provided for the two cases: with the absorption column density nH as a free fit parameter and with nH fixed to the value of 3.5 × 1022 cm-2 measured for the diffuse SNR emission. The mass and radius of the neutron star in the model atmosphere fits are fixed to 1.5 M⊙ and 12 km, respectively. The distances are derived from the normalization constant of the models assuming a stellar radius of 12 km. The indicated uncertainties are at 1 σ c.l.
