Indicator whether the residuals of a fit with excluding CRSF1 indicate a missing model component at 35 keV.

Indicator whether the energy, width, and strength of CRSF1 be constrained in a spectral fit.

Improvement in statistic upon inclusion of CRSF1 in the spectral model.

Number of false positives out of 100 000 simulated spectra where Δχ² exceeds the corresponding value upon inclusion of CRSF1.

Final evaluation whether CRSF1 is detected in the corresponding phase bin.
