From the Challenge 17 lsm file, we generate an observation (with calico-view-ms.py) of two sources of different flux (10 Jy and 3 Jy). The center source is disturbing the observation of the fainter source, which is a bit shifted from the center. This Purrlog simply shows the robustness of the data facing a heavy and simple substraction. Maybe nothing new here but still a applied example of calico-wsrt.py.

Editing the LSM file to keep only the stronger source (see the lsm file below), we are able (using calico-wsrt.py and sky model substraction mode) to substract the stronger source (seen as embarassing the observer) which altered the observation of the fainter source (source of interest). The integrity of the data seemed to be good (as far as I can say...)
