-Retrieve the galaxy cluster catalog simulated by the *Hubble Volume Project*:
-
- http://wwwmpa.mpa-garching.mpg.de/galform/virgo/hubble/
-
-The data used by this package is the *cluster catalog* of the *deep wedge*
-assuming the *ΛCMD* lightcone geometry,
-and can be downloaded from:
-
- http://www.mpa-garching.mpg.de/galform/virgo/hubble/lcdm.DW.tar.gz
-
-The catalog data is downloaded, extracted, transformed, and finally saved
-to a CSV file.

-Catalog Description
--------------------
-The Hubble Volume Project is a joint effort of the Virgo Consortium and
-Collaborators in U.S., Canada, U.K., and Germany. To study the formation
-of clusters of galaxies, filaments and void-structures, a significant
-fraction of the entire observable Universe is modeled and simulated by
-employing one billion (1e9) mass particles. [Evard2002]_
-
-The ΛCDM cosmological model, one of the two models adopted by the Project,
-has the following parameters:
-
- Ω_m = 0.3, Ω_Λ = 0.7, h = 0.7, σ_8 = 0.9
- Cube side length: 3000 h^-1 Mpc
- Main slice: 3000 x 3000 x 30 h^-3 Mpc^3
- P^3M: z_init = 35, s = 100 h^-1 kpc
- 1000^3 particles, 1024^3 mesh
- M_particle = 2.25e12 h^-1 M_⊙
-
-The retrieved catalog of the galaxy clusters is derived from a *spherical
-overdensity* method applied to the *deep wedge* light-cone particle data,
-with overdensity threshold Δ=200. The deep wedge lightcone covers
-10x10 deg^2, with a maximum LoS distance of 5100 h^-1 Mpc, and a redshift
-coverage limit of 4.37. The coordinates used in the catalog are mapped
-to 0-1 unit, and as for the deep wedge catalog, the origin is at (0, 0, 0),
-and is directed toward (1, 1, 1).
