Repository for the "The history and mass content of cluster galaxies in the EAGLE simulation" by Cristóbal Sifón and Jiaxin Han.

Only the hbt folder contains code and data used in the paper. All other folders are leftover code from original exploration of EAGLE's subfind catalogues and initial tests.

The hbt/hbtpy folder contains functionality to deal with the HBT+ catalogues (contact Jiaxin Han to request access).

Figures in the paper were produced from the following:

• Figure 1: fit_relations.py
• Figures 2, 3, 4, 5, 7, 8, and 12: make_plots.py, which calls plot_relations.py. In the latter, modify the functions wrap_relations_distance (Figs. 3 and 12), wrap_relations_hsmr (Figs. 2, 4, and 5), and wrap_relations_time (Figs. 7 and 8), specifying the xcols, ycols, bincols, and selection_kwds appropriately.
• Figure 6: compare_times.py
• Figure 9: shmr_history.py
• Figures 10, 11, B.1, and B.2: preprocessing.py
• Figure 13: massloss.py
• Figure A.1: orphan.py

All of these are run, at a minimum, with the following signature:

python fit_relations.py L100 path/to/hbt/data

Most of these require first having run store_subhalo_times.py to generate historical information.
