Main parameters of the best fits obtained by adding three BVAPEC components to the enhanced abundances TMAP model and allowing the nitrogen abundance to vary. The flux is the unabsorbed one. The N(H) minimum value of 3 × 1020 cm−2 and the fit converged to the minimum value in the second and fourth observations. We also assumed a minimum BVAPEC temperature of 50 eV.
