Top-left: Hi-GAL 500 μm (or JCMT 850 μm) continuum image in contours overlaid on the Spitzer/IRAC 8.0 μ (or MSX 8.3 μm) image in color scale. The box show the region mapped with the IRAM 30-m telescope. Top-right: nine panels with the zero-order moment (velocity-integrated intensity) maps of different molecular species (labeled in the top-left corner of each panel). The minimum and maximum contour level (in units K km s^-1) is indicated in the bottom part of each panel. Bottom: four panels with the IRAM 30-m spectra at 3 mm, covering a frequency range from 87.6 GHz to 93.4 GHz.
