Project         Explanation
------------------------------------------------------------------------------------------

boxptl_*        Filenames starting with boxptl_ contain general particles from the 
                simulation and know nothing about galaxies. Those datasets are useful for
                computing lensing. Numbers such as _20m and _50m indicate the number of
                particles in the files (e.g., 20 million).

stellarmaps     Stellar maps of massive galaxies, typically centrals only. For each 
                galaxy, the maps are split into insitu/exsitu and into particles bound to
                the galaxy (subhalo), particles in other subhalos in the same FOF group,
                and particles not bound to any other subhalo (fuzz). The maps come in 
                low and high resolution (lr and hr), corresponding to the same number of
                pixels but different physical extents of the maps.

agez            Similar to stellarmaps, but with maps of stellar metallicity and age and
                only for bound particles.

rsd             Galaxy catalogs with halo mass accretion histories (MAHs). The key is 
                that there are files for both baryonic and dark-only simulations, with 
                matched halo IDs.

clusterfinder   Stellar maps for massive galaxies including centrals and satellites, as 
                well as star formation histories (SFHs) and MAHs for the halos, the 
                former split by insitu and exsitu.

catalog         Mostly catalog data, but for a larger mass range. The files can also 
                contain additional non-catalog fields such as the insitu mass fraction.
