    Description

      This feature will test the scientific performance of the YANDASoft constrained calibration solver. The robustness of the solver to known discontinuities in spectra will be tested using ASKAP data with phase jumps every 54 channels due to independent PAF beam-former solutions.

      An example showing these discontinuities is given below. This is an extreme example dating from before changes were made to regularise the beamforming, however small phase discontinuities are still present.
