Bayesian inference results for gas properties traced by HNCO (green) and SiO (blue) of CND-R1 region. The corner plots show the sampled distributions for each parameter, as displayed on the x-axis. The 1D distributions on the diagonal are the posterior distributions for each explored parameter; the reset 2D distributions are the joint posterior for corresponding parameter pair on the x- and y- axes. In the 1D distributions, the 1σ regions are shaded with blue; both 1σ and 2σ are shaded in the 2D distributions.
