Table B.1

The various total, soft and hard energy bands of the catalogs considered in this work. For the total band, we indicate the fraction of reference total flux (0.1–12 keV for a spectrum with Γ = 1.7 and N_H = 3 × 10²⁰ cm⁻²) this band contains. This allows us to calibrate the various catalogs, assuming this underlying spectral shape. For the soft and hard bands, we show the threshold in hardness ratio above (resp. below) which a detection is in the 10% hardest (resp. softest) of its catalogs, which could lead to errors of factor of ~ 2 in the flux calibration and, thus, in the variability computation.
