This directory contain the mock halo--galaxy--supermassive black hole mock catalogs generated with the Trinity code (Zhang et al. 2023, https://doi.org/10.1093/mnras/stac2633). If you decide to use these catalogs in any published results, please cite Zhang et al. (2023, https://doi.org/10.1093/mnras/stac2633). These mock catalogs are generated based on the MultiDark-Planck (MDPL2) N-body simulation (Klypin et al. 2016, MNRAS 457, 4340), with a box size of 1 Gpc/h, 3840^3 particles, and resolves 10^11 Msun halos. The halo catalogs are generated by the Rockstar halo finder, developed by Peter Behroozi (Behroozi, Wechsler & Wu, 2012, https://iopscience.iop.org/article/10.1088/0004-637X/762/2/109). For the instruction and examples of how to read the catalogs, please see the loader.py files in this directory.
