Notes. The main parameters for each source are given: name of the source, duration of the outbursts τ_QPE in hours, recurrence time T_rec in hours, BH mass M_BH estimated from blackbody radiation in quiescent state, mass accretion rate Ṁ during the outbursts in Eddington units Ṁ_Edd, and maximal and minimal luminosities in the range 0.5 − 2 keV.
