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 |
