Slopes of the linear fits to the dependence of the spectral parameters on flux with the corresponding Pearson correlation coefficients and the associated two-sided null-hypotheses probabilities (a lower value indicates higher significance of the correlation).

Notes.The uncertainties for the slopes are at 1σ confidence level. The parameters from the pulse-phase resolved analysis of the phase intervals 0.1–0.5 (main peak) and 0.6–1.0 (secondary peak) are shown in the top section (for Γ, Erolloff was fixed to 16 keV). In the bottom section, the values from the pulse-to-pulse analysis are shown. For the fit of Γ we fixed Erolloff = 15.5 keV for INTEGRAL and Erolloff = 15.2 keV for RXTE. For comparison, the values from Klochkov et al. (2011) are also shown.
