Notes. ‘Model’ column lists the spectral ageing model fitted to the data. ‘Average
’ column list the average 
of the fit over the entire lobe. ‘Confidence bins’ columns list the number of regions for which the χ2 falls within the labelled confidence range. ‘Rejected’ column lists whether the goodness of fit can be rejected over the entire source. ‘Median confidence’ column lists the median confidence level at which the model cannot be rejected.
