== Multi Frequency Synthesis Clean ==
Add a spectral curvature term (2nd order term) to mfclean. 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.
A substantial amount of testing will be needed to complete this item.
