SVD Did not converge #2

Open ELLI-E opened 1 week ago

ELLI-E commented 1 week ago

Ran code on object 39627770262716602. Received following error log. Attempted to run with and without masking nearby sources without any changes. decompositionError.log

This error means the fitting with PSO algorithm could not converge, very likely beacause of source No.4 at the edge. It is truncated and cannot be well-fitted with a sersic profile. Suggestion would be masking that source.

Here is the data used for the fit with the companions masked, and the corresponding error log. It doesn't seem to make much difference

Maybe there are infinite or nan numbers in your data? Try drop those pixels as well if any?
