Notes. We explore a wide range of parameter spaces for the models listed in column 2 and their properties detailed in column 3. For each, we show the fraction of gas available for accretion onto the black hole (column 4), the maximum threshold efficiency for star formation (column 5), and the fractions of black hole and SNII feedback energies that can couple to gas (columns 6 and 7, respectively).
