vmax.fits

Contains the maximum volume over which each galaxy in a subsample is observable, given the flux and redshift limits. The header indicates what it assumes about the evolution (in the Q0, Q1 and QZ0 header cards).

The columns are:

  1. ZMIN_LOCAL: The minimum redshift observable for a galaxy with this absolute magnitude in this direction (i.e. with the bright limit in this direction).
  2. ZMAX_LOCAL: The maximum redshift observable for a galaxy with this absolute magnitude in this direction (i.e. with the bright limit in this direction).
  3. VMAX: The total volume over which this galaxy is observable in the current subsample (accounting for the fact that other directions may have different flux limits)
  4. ABSM: The absolute magnitude of the galaxy
