Figure of merit (FoM) for the galaxy power spectrum and the cosmological parameters for regular and random sampling.

FoM Power spectrum Cosmological parameters

Design Regular Random Regular Random

Entropy 39.3 39.2 3.5 3.5
D-optimality 1415.5 1415.9 11.2 11.3
A-optimality 20.6 20.6 7.8 7.8

Notes. The FoMs are defined so that they need to be maximised for an optimal design.
