Resulting joint posterior distributions for temperature and density as produced for the high resolution (∼40 pc scale data) for the nine regions that have enough ratios to fit. The temperasture and density values shown in Table 6 are from distributions visualised in this plot. It must be noted that the median values of these distributions, as shown in Table 6, do not always correspond to the most densely populated areas of the corresponding plot. This is due to the extent of the posterior distribution in the temperature plane.
