Voids catalogue (dr1.Voids)

The table has 15 rows, 12 columns.

Description

This table describes the main physical properties of CAVITY voids. All the properties are directly taken from Pan public void catalogue [1]. Their assumed cosmology is Omega_l = 0.73 and Omega_m = 0.27. All x, y, z coordinates are calculated as distances in Mpc/h, following equations below:

  • x = r · cos(ra) · cos(dec);
  • y = r · sin(ra) · cos(dec);
  • z = r · sin(dec).
