| | 14 | || '''Stage''' || '''Description''' || |
| | 15 | || 1 || Basic handling of CABB data. Strong frequency dependencies ignored.|| |
| | 16 | || 2 || Use of wide "continuum" bands to calibrate zoom bands. 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. || |
| | 17 | || 3 || 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. || |
| | 18 | || 4 || Wide bands handled explicitly: calibration and imaging tasks become frequency dependent, removing the limitations imposed by the technique used in stage 2.|| |
| | 19 | || 5 || New algorithms for high-dynamic range imaging and polarimetry || |
