\caption{Physical parameters of the clumps found in the $^{13}$CO
2$\;\to\;$1 map of the CygX-North region.  The columns indicate:
(1) the running number of the clump shown in Figs.~\ref{clouds1}$-$\ref{clouds6};
(2) the center velocity of the clump emission derived from the clump
averaged $^{13}$CO~2$\;\to\;$1 spectrum;
(3) the line width of the $^{13}$CO~spectrum averaged across
the clump;
(4) and (5) $^{12}$CO~and $^{13}$CO~2$\;\to\;$1 main beam brightness
temperature determined at the position of peak emission;
(6) excitation temperature derived from $T_{\rm mb}$($^{12}$CO);
(7) excitation temperature derived from the $^{13}$CO~3$\;\to\;$2/2$\;\to\;$1 line ratio;
(8) opacity calculated from $T_{\rm mb}$($^{13}$CO) and $T_{\rm ex12}$;
(9) total $^{13}$CO~column density;
(10) H$_2$ column density;
(11) mass of the clump;
(12) Equivalent Radius ($r$~= (area/$\pi$)$^{0.5}$ with the area
determined by the polygon), deconvolved with the beamsize; and
(13) average $n$(H$_2$) density, assuming a spherical cloud.}
