Notes to the table: a The volume density and column density are inferred from HCN and H2 observations. b The volume density and column density are inferred from OH 1720 MHz maser observations. The offsets are the reconstructed pointing offsets and the numbers in the parentheses are the 1$\sigma$ statistical uncertainties. Upper limits are 3$\sigma$.
