The errors in the estimates of source position and flux after the sourcefinder step in TraP are calculated based on Condon (1997), Condon et. al. (1998). Equation 17 of the TraP paper mentions absolute values for certain parameters (alpha_m, alpha_M etc.). We need to confirm whether these values can be used unchanged on AARTFAAC images or not.

One possibility is to look at the flux and position estimations + their errors for individual sources and then generate histograms of the offsets of the parameters from catalog values. Then see how the errors compare with the theoretical values as determine by the Condon paper.
