Columns~2 and 3: velocity integrated intensity of the \coone\ and
\two\ lines. The temperature refers to the main beam temperature 
scale ($T_{\rm mb}$).
Upper limits were derived as discussed in Sect.~\ref{sec:results}.
Columns~4 and~5: FWHM and central velocity of the \one\ line derived from 
Gauss-fits to the line, except in the case of NGC~7741 (see text). 
Columns~6 and~7: molecular gas mass derived with a constant~(6) and
luminosity-dependent (7)~conversion factor (see Sect.~\ref{subsec:gasmass}).  
The values for NGC~5584 (flagged with a~$*$) were derived
from the \two\ line intensity.
Column~8: atomic gas mass, calculated from the $21\cm$ flux.
See Sect.~\ref{subsec:gasmass} for details.
