Phase-resolved X-ray spectra of the SRGE0758. The black data points represent the bright phase spectrum and were extracted for the phase interval 0.8 − 1.2. The black line shows the model fit with a reduced chi-square value of 1.02 (χ = 171 for 168 d.o.f.). The spectrum of the first dip (shown with red data points) was obtained from the phase at 0.4 − 0.5. The fit revealed a reduced χ² of 1.51 (χ = 30 for 20 d.o.f.).
