$^a$ For the determination of $L_{\rm FIR}$ and $T_{\rm dust}$ (60/100~$\mu$m color 
   temperatures), see Wouterloot \& Walmsley (\cite{Wou86}). The IRAS fluxes were taken from Fullmer 
   \& Lonsdale (\cite{Ful89}) and, for a few sources (NGC~598, NGC~4258, IRAS~F19370--1031 and 3C~403), 
   from NED. While, as already noted by HWB and Braatz et~al. (\cite{Bra97}), the derived dust 
   temperatures are mostly well above 30~K and thus rather large, a correlation between 
   $T_{\rm dust}$ and $L_{\rm H_2O}$ is not apparent. \\
