Notes. ^(a) Intensities with uncertainty in between brackets. ^(b) Beam-averaged column densities using RADEX with n=10⁵ cm^-3 and T = 85 K, with estimations for 50 and 150 K in between brackets. ^(c) Beam-averaged column densities in the high-density (LTE) limit for 85 K, with estimations for 50 and 150 K in between brackets. ^(d) Note that the density (or temperature) could be higher than assumed, which would decrease the column density, and the para-H₂O 2 line could be affected by IR pumping. ^(e) We used the HCO⁺ line because the HCO⁺ line is possibly blended with an HCl line. Column densities from ¹²CO and ¹³CO lines are uncertain due to high optical depth and are not listed.
