Posterior probability density distributions from our analysis of the NICER data on PSR J0437−4715, where the units are the same as in Table 5. Here, we use our featured model, which has three uniform-temperature circular hot spots plus a modulated power-law spectrum with a Gaussian profile in rotational phase. The power-law normalization NPL is in units of 10−5 keV−1 cm−2 s−1.
