Measured diagonal of the covariance matrix for 7375 power spectra realisations of the density field using the Monte Carlo method (black line) up to kN ∼ 0.67 h Mpc−1. The other curves represent their predictions taking into account the Gaussian part alone (G) or by adding some non-Gaussian contributions of Eq. (15). For example in (1-NG) only the term in 𝒫3(ki) is kept in the tri-spectrum development presented in Eq. (17), while in (3-NG) all of them are kept.
