We elucidate the affect of aliasing and the varying form of HEALPix pixels on energy spectra and show how the HEALPix pixel window function approximation is made in the discrete spin-2 setting. We propose several improvements to the usual estimator and its modelling, based on the principle that supply positions and weights are to be considered fixed. We present how empty pixels might be a..."
