Plot of light curve, HR, and best-fit parameters as a function of time obtained from the HR-resolved spectral analysis of the XMM-Newton observation of IGR J11215−5952. Panel a: source count rate in the 0.5–10 keV bands, after adaptive rebinning with minimum S/N of 15 in the light curve extracted for 0.5–3 keV; panel b: HR between the 3–10 keV and 0.5–3 keV energy-resolved light curves with the identified time intervals for the spectral extraction (red lines); panel c: f, covering fraction of the partial absorber; panel d: Γ, power-law photon index; panel e: N_H, absorption column density along the direction to the source (including Galactic absorption); panel f: N_H, pc, absorption column density of the partial absorber (representing the absorption column density local to the source; PCFABS in XSPEC); panel g: F_{2 − 10 keV}, measured power-law flux in the 2–10 keV energy range not corrected for absorption for the EPIC-pn in units of 10⁻¹² erg s⁻¹ cm⁻².
