Return value

Parameters

table in required

Array of structures with fields {coeffs:, z:} and columns for absolute values given in vars. Redshift z is optional: raises warning if outside observable limits.

vars in required

Array of structures with fields {abs_name:} giving the column name in table corresponding to the absolute value, {band:} giving the name of the band, {type:} giving 'M'agnitudes, 'S'urface brightness or 'R'adius and {app_min:, app_max:} giving the limits.

Keywords

zmin in optional

Minimum redshift. Default = min(table.z) or 0

zmax in optional

Maximum redshift. Default = max(table.z) or 2

area in optional

Area of survey in square degrees. Default whole sky.

q0

q1

z_min_limited_by out optional

Number of galaxies with minimum redshift limited by each of the variables, or by zmin

z_max_limited_by out optional

Number of galaxies with maximum redshift limited by each of the variables, or by zmax

v out optional

Volume, as in V/Vmax, for each galaxy
