You can also look at the directory structure directly, that way it's easier to see which simulations have actually been run through the radiative-transfer code. The number of SPH simulations vastly outnumber the radiative transfer simulations, so if you click on a run and get a 404 Page Not Found error, that's what's going on.
Clicking on a run then takes you to a sub directory which contains all the variations of the simulation with different radiative-transfer parameters. The naming convention is usually something like "0.4Zsolar-imf2.35", which indicates that the simulation was started with a metallicity of 0.4 solar and that the upper IMF slope is Salpeter. "cZsolar" means constant metallicity, i.e. with metal enrichment turned off. "SMC" means that the SMC dust characteristics was used unlike Milky Way which is default. A few other variations may exist.
