Narrowing down the parameter space of QPEs.

Source	Collision cond.	Disruption cond.	Implications
GSN 069	1.9–2.2	1.2	↓β
eRO-QPE1	2.9–3.5	0.7	↓β + ↑M_dis
eRO-QPE2	0.6–0.8	2.9	↓M₁
RX J1301	1.3–1.5	1.9	↓β, ↓M₁
Swift J0230+28	32–36	0.1	long after t_vis
eRO-QPE3,4	3.0–3.7	0.7–1	↓β + ↑M_dis
eRO-QPE5	11–13	0.3	long after t_vis

Notes. Both conditions should yield a number ≤1. In the rightmost column are the modifications that could correct the discrepancies – modifications point to smaller or larger values. The conditions follow from (20) and (11). The ranges of values in column 1 come from the SMBH uncertainties.
