ALMA results in the Chamaeleon complex. Center: RGB image with N(HI) in blue, N(DNM) in green and Nanten CO emission brightness in red. The locations of the 13 ALMA sources studied in Paper I are marked as squares, hatched for the 5 directions where CO absorption was detected in this work. The positions of 8 stars with measured values of N(H₂) and N(CO) in UV absorption (Table 3) are marked by x’s. Shown around the outside are HCO ⁺ (grey, shaded) andCO (red) absorption and CO emission profiles (blue) from NANTEN on a different vertical scale as noted at right in each outer panel. CO absorption was not observed toward J1723 and was sought but not detected or plotted toward B1251.
