\caption{Height differences, $\Delta h$, of solar emission with respect
to the hump~1 obtained by cross-correlations calculations between limb brightening curves
from slit (Fig.~\ref{subKBr}a) and hole (Fig.~\ref{hole}) observations.
The rows named "average'' refer to averages above the horizontal dashed-dotted lines.}\label{tab2}
