Merger Tree of halos and sub-halos
TreeMaker (version 2) is the second step of the GalICS pipeline. From the
tree_brick_xxx computed by HaloMaker2.0, it creates a merger tree including all
halos detected by HaloMaker2.0 in the provided snapshots.
TreeMaker2.0 works the same way whether there are sub-structures (detected by
Adaptahop) or not.
This program creates two kind of output. The file tree.dat which contains the
merger tree and all data concerning halos (including the structure tree). This file is needed to use GalaxyMaker,and create catalogs of galaxies.
The second output are the files halos_results.xxx where xxx is the number of
the snapshot. It contains all the properties of each halo for a given snapshot.
