Notes.  The numbers in parentheses represent the errors in units of the last significant digits. (a) Intrinsic line strength. (b) Obtained by the Gaussian fit. (c) The rms noise at an emission free region averaged over the line width. For non detected lines, the line widths of 0.5 km s-1 are assumed. (d) Calculated on the basis of the rest frequencies of the C13CH lines obtained in this study (Table A.1). (e) Marginal detection. (f) See Sect. 3.1 and Appendix A.
