Column 3 gives our measured values. The last column gives the IRAS measurements (Pottasch et al. 1986, and new unpublished data) below 20 $\mu$ m, and the values of Liu et al. (2001) 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.
