Distributions of physical parameters derived from the 13CO observations. (a) Optical depth (﹩{\tau }_{{}^{13}{\rm{CO}}}﹩) of the 13CO line. (b) CO-based H2 column density, ﹩{N}_{{{\rm{H}}}_{2}-{\rm{CO}}}﹩, in units of 1021 cm−2. Histograms show the TRAO data (this work) and the PMO data from Y. Wu et al. (2012). Solid curves represent lognormal fits with the best-fit parameters (μ, σ) indicated.
