Notes. Region column lists the different regions as shown in Fig. 7. The first four columns list the flux densities. αinj column lists the best fit injection index. Beq, 0 and Beq, 10 column list the magnetic field estimate with κ = 0 and κ = 10, respectively. tspec, 0 and tspec, 10 list the spectral ages estimated using Beq, 0 and Beq, 10 respectively. 
column lists the reduced chi-squared (for two degrees of freedom) for the JP model fit.
