Significance of the deviation between low-frequency lag-energy spectra of two stacked observations in AGNs without UFOs (Similar to Fig. 3).

Names	$P_{null}^{Cal}$ $P_{\mathrm{null}}^{\mathrm{Cal}}$	σ_Cal	$P_{null}^{MC}$ $P_{\mathrm{null}}^{\mathrm{MC}}$	σ_MC
Ark 564	0.90	0.12	0.96	0.05
NGC 7469	0.96	0.05	0.97	0.03
Mrk 335	0.26	1.12	0.27	1.09

Notes. Both two approaches confirm that, in AGNs without UFOs, the low-frequency lag-energy spectra of the low-flux observations are consistent with those of the high-flux ones.
