The natural-weighted 3mm continuum map with a 0.5” uv-taper (gray scale) with contours overlaid from the IRAC-3.6 μm map (red isocontour levels at 3, 6, and 12σ). Sources that revealed CO (2-1) line emission are marked with open blue stars, while the continuum detections reported in Table 4 are marked as blue circles. The potential 3σ continuum detection toward an IRAC source is marked with a blue square.
