Asymptotic connection between full- and flat-sky angular correlators
We investigate the connection between the full- and flat-sky angular power spectra. First, we revisit this connection established on the geometric and physical grounds, namely, that the angular correlations on the sphere and in the plane (flat-sky approximation) correspond to each other in the limit...
