Cosmological inference including massive neutrinos from the matter power spectrum: Biases induced by uncertainties in the covariance matrix

Open Access

Fig. 16.

Ratio R between the parameter uncertainties obtained with the non-Gaussian covariance C^iNG and the Gaussian one C^G. In the left panel we only consider the contribution to the diagonal and in the left panel off-diagonal terms are also accounted for. The dashed and plain lines correspond respectively to the uniform and Gaussian BBN priors on ω_b.
