Fig. 3


Intensity cuts along the reversed right-ascension axis at the constant declination of the envelope components of Sgr B2(NE), Sgr B2(N), Sgr B2(M), and Sgr B2(S) from top row to bottom row. The data is plotted in solid black. The wavelength decreases from left to right: 870 μm, 500 μm, 350 μm, 250 μm, and 70 μm. Model A is denoted by the circular markers, Model B by the squared markers, Model C by the diamonds shaped markers and model D by the triangular markers.
