Notes. (*)Values with large uncertainties are derived from the tentative detection of C36S lines. (**)For these three sources without parallax data, their kinematic distances were estimated (for details, see Sect. 2.1). The 34S/36S and 32S/36S isotope ratios in this work from the J = 2−1 transition are corrected for the optical depth effects, while the ones for the 3−2 line could not be corrected.
