Notes. The first column indicates the total mass of the parent gas cloud, the second specifies the number of frequency groups used in each run and the penultimate one indicates the upstream Mach number of the flow at the accretion shock. The final column lists the time at which the density at the centre of the grid reached ρc (the time is independent of the number of groups used). The other quantities are explained in the text.
