    Description

      This feature will test the scientific performance of the YANDASoft constrained calibration solver. The robustness of the Laplacian smoothing constraints described in --YAN-189-- to gaps in spectra caused by broad-band RFI will be demonstrated using ASKAP data.

      Some example ASKAP bandpasses with RFI gaps are shown below.
