Notes. The rms values are standard deviation over line-free channels. Uncertainties on Vlsr, σV, Ncol, and a one-dimensional turbulent Mach number are expressed as 95% high-probability density intervals. (a) Optical depth of the o- H2D + transition, expressed as average value ± standard deviation around the average within each core. The values were computed assuming Tex = 10 K.
