Column~3 gives our measured values. The last column gives the IRAS measurements
  (Pottasch et~al. \cite{pott3}, and new unpublished data) below
  20~$\mu$m, and the values of Liu
  et~al. (\cite{liu}) above 50~$\mu$m. All intensities are in units 
of 10$^{-12}$ erg~cm$^{-2}$~s$^{-1}$. The ":'' on some line
intensities indicates uncertain values.
