Two-parameter constraints for different masks and different combinations of covariance contributions: Gaussian (G), super-sample (SS), and connected non-Gaussian (CNG). Shape noise is included, following Eq. (9). In each panel, all parameters other than the two shown are held fixed. Only the 1 and 3σ confidence regions are marked, which respectively contain the highest 68.3 and 99.7 per cent of the posterior probability mass. The relative areas of each 3σ confidence region are listed in Table 1. We note that the axis ranges differ between panels.
