Spectrum of PSR J1357−6429 detected with the Chandra ACIS-I instrument (crosses in the upper panel) and fitted with a NSA-plus-PL model (solid curves). The thermal (NSA) component, as well as the hydrogen column density, is the same as in Fig. 2. The dashed curve indicates the PL component derived from the EPIC spectra. The lower panel shows residuals in the spectral fit.
