SubLink catalogs

The folders SubLink and SubLink_gal contain the SUBFIND-based SubLink and SubLink_gal merger trees. The data is organized following the general hierarchical structure described in Suite folders.

The format of the catalogs is the traditional one from SubLink, and we refer the user to the SubLink documentation for further details. We note that these trees are not yet available for SIMBA, but for now only for IllustrisTNG and Astrid.

We make available both SubLink and SubLink_gal versions generated by the SubLink algorithm. SubLink is the dark matter-based version, which corresponds exactly to the method used in the public data release of the IllustrisTNG project, while SubLink_gal is the baryonic-based version, which tracks the baryons across snapshots rather than the dark matter. The differences between the two are modest.
