[ascl:2108.003] MAPS: Multi-frequency Angular Power Spectrum estimator

MAPS (Multi-frequency Angular Power Spectrum) extracts two-point statistical information from Epoch of Reionization (EoR) signals observed in three dimensions, with two directions on the sky and the wavelength (or frequency) constituting the third dimension. Rather than assume that the signal has the same statistical properties in all three directions, as the spherically averaged power spectrum (SAPS) does, MAPS does not make these assumptions, making it more natural for radio interferometric observations than SAPS.
