| Abstract: |
The CLEAN algorithm, despite its problematic convergence properties and its need for heuristic intervention and tuning, is the most commonly used means of attenuating sampling artifacts in images made through radio interferometry. Subsequent modifications adapted CLEAN to observations made using a wide fractional bandwidth, which are not well handled by the original algorithm. Here a generalized version of the wide-band algorithm is applied to time-variable sources. |
