Summary figure for the 7 and 12 m line observations. Columns from left to right show the results of C¹⁸O(2–1), ﹩{{\rm{N}}}_{2}{{\rm{D}}}^{+}﹩(3–2), ﹩{\mathrm{DCO}}^{+}﹩(3–2), and ﹩\mathrm{DCN}﹩(3–2). From top to bottom, the color scales show the maps of 7 m moment 0, 7 m moment 1, 7 m+12 m moment 0, and 7 m+12 m moment 1. The color bar on the right indicates the flux scale in Jy beam⁻¹ for moment 0 maps and velocity in km s⁻¹ for moment 1 maps. The black contours illustrate the 1.3 mm continuum emission for comparision, with the first two rows showing 7 m continuum images and the last two rows 7 m+12 m images.
