Comparison with DarkEmulator2

• The relation used by MTU between \(P_\mathrm{cb}\) and \(P_\mathrm{tot}\) is

P_\mathrm{tot} = (P_\mathrm{cb}^2 + P_\mathrm{\nu}^2)^{1/2} .

• Therefore, the comparison with the DE2 cb component should be interpreted only as a diagnostic, because the component definitions appear to differ.

P_\mathrm{tot}^2 = P_\mathrm{cb}^2 + 2 P_\mathrm{cb} P_\mathrm{\nu} + P_\mathrm{\nu}^2
