\tablefoot{Column~1: region;  Col. 2: observed Burn law $\langle k\rangle$. 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.}
