LWS spectrum of the dark molecular cloud SgrB2.
The OI 63 micron absorption line overlaid on an 8.4 GHz VLA
image of Sgr B2 showing a 4.4 x 4.4 pc field centered on the luminous
FIR source Sgr B2 M. The width of the box (80") is the FWHM diameter
of the ISO LWS beam; the spectral resolution of the LWS FP at 63
microns is 37 km/s. (Keene, J. et al.)
