A semi-analytic covariance matrix for ACT DR6 power spectra, combining inhomogeneous survey-depth weights and a simulation-based eigenbasis correction, reaches sub-percent agreement with Monte Carlo simulations.
A field that follows the model of Equation 9 has zero mean and is Gaussian, so its statistics are fully specified by its covariance
