Notes. (1) Corresponds to the name of the model; (2) free parameter regulating the transfer of gas to the NSC gas reservoir; (3) efficiency parameter describing the fraction of the stellar mass converted into a BH seed once the cluster exceeds the critical mass; (4) efficiency parameter described in Sect. 2.2.1; (5) denotes the minimum NSC mass adopted in the respective model.
