\caption{Examples of distances of CVs determined by the surface
brightness method.  Columns (1) to (4) contain information of the
secondary star, Col.~(5) the contribution of the secondary star to
the observed flux at~7500~\AA, Cols.~(6) and~(7) the $V$ and
$K$-magnitudes of the secondary star, Col.~(8) the mass used in
calculating the distances $d_{\rm 7500}$, $d_{V}$, and $d_{K}$ in Cols.~(9)$-$(11), and Col.~(12) gives the
trigonometric distance if available. See text for errors of the
quantities in Cols.~(4) to~(8).}
