Columns~3$-$5: normalization constant $C_0$, fitted maximum spatial frequency $f_{\rm max}$ for the best CPL power spectrum of each region and the predicted $\langle k\rangle$ for each power spectrum. Columns~6,~7 as Cols.~3 and~5 but for the joint fit to each CPL power spectrum; Cols.~8 and~9 as Cols.~3, and~5 but for the joint BPL power spectrum. For both the joint CPL and BPL fits, the maximum frequency is fixed at $f_{\rm max}= 1.67~{\rm arcsec}^{-1}$. In calculating each value of $\langle k\rangle$ only data with $p>4\sigma_p$ are included.} \end{table}
