Data used in “Tracing the Cosmic Web” comparison project
The data for this project is available for download as a zipped tar file: TracingTheCosmicWebData.tar.gz.
This directory contains two types of files: CUBE and FOF, also see the README.txt.
The simulation that the methods were run on had following parameters:
|Lbox||200 Mpc/h||side length of simulation box|
|Nparticles||512^3||total number of simulation particles (resolution)|
Terminology/convention for the cosmic web classification:
FOF_200_512_<method>.txt**CUBE file format:** The cosmic web classification of each point in space is returned on a regular grid of 2 Mpc spacing. The first three columns give the (x,y,z) coordinate of the cell's center. The last column returns the "web_id", described above. **FOF file format:** Each method was asked to add a final column to the FOF catalog with the "web_id". The meaning of the other columns may be ascertained from the header in the FOF catalog: fof_catalog_200Mpc512.txt (b=0.2 linking length). We include the gadget z=0 snapshot directory as well (`./snapshots`).
