This is my first Purr log to report my attempt of substracting a strong source from the observation. This is just a GUI manipulation training including no code modification. I used the example-sim.py program to generate the simulation of two sources and the Cattery/Calico/calico-view-ms.py program to try remove the stronger source.
I will start with the .lsm file from the challenge n# 17 and try to remove the stronger source (10 Jy) to only keep the fainter source (reduced to 1 Jy)

Given the previous .lsm file and the instructions of Open Challenge N# 1 and 17, we can generate the following dirty image of the two sources:
1 center source, 10Jy & 1 near center source, 1Jy
The next step is to modify by hand the .lsm file and, according to Open Challenge #1, and substract the stronger source using Cattery/Calico/calico-wsrt.py.

So, after editing the .lsm file to erase the fainter source line, I try to load the sky model in the calico-wsrt.py compile time. However, LSM.py can't manage to read the .lsm file. Even if I take the .lsm file of Open Challenge #1 (which is representing a 10 Jy source at the center), a compilation error occur (see screenshot below...)
How could I do my substraction? Is this the correct method? I am stuck...
