== Project Stages ==

|| '''Stage''' || '''Description''' ||
|| 1 || Basic handling of CABB data. Strong frequency dependencies ignored.||
|| 2 || Strong frequency dependency handled  using the 'divide and conquer' approach; that is, split up the 2 GHz CABB band into a number of sub-bands for which the existing calibration tasks are adequate. Continuum images will be sums of deconvolved images from the sub-bands, limiting the image quality. ||
|| 3 || Use of wide "continuum" bands to calibrate zoom bands.  ||
|| 4 || Data flagging on the basis of autocorrelations; single dish analysis modes. Broad bands and data volume is expected to make automatic flagging highly desirable, or essential. ||
|| 5 || Wide bands handled explicitly: calibration and imaging tasks become frequency dependent, removing the limitations imposed by the technique used in stage 2.||
|| 6 || New algorithms for high-dynamic range imaging and polarimetry ||
