Antenna Beam Modeling #67

This is an important part of enhanced calibration as well as new inference algorithms. This issue is a placeholder. Andre Offringa suggests EveryBeam as a package that can model beam patterns. Meerkat uses FITS images - however Andre says this is inefficient as one needs a different image for each antenna and each frequency and for each elevation. By expanding the beam in basis functions, one can interpolate in frequency space to calculate beams at different frequencies.
