Unfolded spectrum of J1301. Red and black dots are for the FPMA and FPMB telescopes of the NuSTAR observatory (NuSTAR2024), green for the Swift/XRT telescope. Gray dots represent NuSTAR2014 observation (Krivonos et al. 2015). The solid blue line in panel a shows the comptt+comptt spectral model, while the dashed blue lines represent the two components separately. The dashed magenta line shows the best fit with the absorbed cutoff power-law model. A blackbody model with temperature T = 1.0 keV is plotted as a dashed gray line for visual comparison. Panels b and c show the residuals for the comptt+comptt and cutoffpl continuum models, respectively.
