    73 Again, we can expect gas falling in from something like 10^-6^ pc away from the sink to have enough time to gain a significant fraction of the accretion luminosity from infinity. Therefore, unless we are really modeling distances much smaller than this -- we have shown that really for a wide range of starting kinetic energies, the infinity luminosity should do just fine. As a caveat, the sink radius is so much less than a cell size (it is a sub-grid model, no way of telling its size other than it is small compared to a grid zone).. this implies that these are all ''upper'' limits to the resolution requirements. So basically, it makes sense to use L = G M m-dot/R.
