Distribution of MSE for three subsample of our catalogue. The panels show that the selection of candidates with Prob>80% and MSE<0.25 (top) or Prob=50–80% and MSE<0.2 (middle) allows us to isolate a sub-sample occupying the same parameter space of the golden sample with Prob>90% and S/N>60, here shown in red, that we use as a reference. The bottom panel shows the final sample resulting from the visual inspection (teal) compared with the reference sample (red).
