Notes. The results derive from the modelling of the single NICER spectra using Model 0 or Model 1A, according to the statistical significance of the fit in each case. K_nthc and K_bb are the normalisations of the nthcomp and bbodyrad components, respectively. The unabsorbed flux is estimated in the 0.5–10 keV energy interval.
