Extended Data Fig. 1: Comparison of the fit results for NS mass and radius from this work with those reported by ¹⁴.

The dotted line shows results from the latter work for a fixed distance of 3.2 kpc (1σ credible interval). The labeled contours show results obtained in this work: (1) - same model and energy range as ¹⁴, (2) - same as 1 but with data below 1 keV included, (3) - same as 2 but with the wabs model component substituted with tbabs, (3a) - same as (3) but also accounting for the scattering component, (4) same as (3a) but with distance fixed to 2.5 kpc, and (5) - same as 4 but with distance priors set to the Gaia estimate as described in the text.
