WebThe key science goals of these newcomers will often demand an implementation of more advanced calibration strategies where both direction independent (e.g. receiver electronics) and dependent (e.g. primary beam and ionosphere) effects are taken into account under an unified mathematical formalism such as the radio interferometer measurement equation … WebJun 16, 2024 · We start by describing the telescope primary beam models used in this paper. We concentrate on the MeerKAT single dish observations (autocorrelation signal) and assume for simplicity that all dishes have the same primary beam, since our focus are the frequency effects. This is a fair approach since map making is done separately for every …
