Notes. Theoptically thin LTE line intensity ratio of hyperfine split components is 1:3:5, both for HCN 1-0 and H13 CN 1-0. Hyperfine split components of HCN for Ser SMM9, SMM10, and off-position 4 are blended, and the optical depths cannot be determined. The “–” shows sources with negative values of optical depths obtained from calculations.
