    1818== Multi Frequency Synthesis ==
    1919Add a spectral curvature term (2nd order term) to MFS imaging. At present the average flux and a spectral index are handled. For 2-4 GHz bandwidth we may require higher order terms to model the sources in a typical field, especially at the lower frequencies. Some research is required to determine whether this is indeed a limiting factor in high dynamic range imaging and how much improvement can be expected.
     20== Polarimetry ==
     21[wiki:Changes/polarization Improving polarimetry] requires a beam that scales with frequency; having a beam cube with 1000 channels in it is impractical, according to the practicioners. This change would be required in {{{restor}}} as well.
