LVG result maps for NGC 4826. Upper left: H₂ number density averaged over the 90% confidence interval of each LVG model. The black contours are at 10³ and 5 × 10³ cm^-3 and the white contours at 10⁴ and 5 × 10⁴ cm^-3. Upper right: kinetic temperature averaged over the 90% confidence interval of each model. The black contours are at 5, 10, 20 K and the white contours at 40 and 60 K. Lower left: pressure averaged over the 90% confidence interval of each model. The black contours are at 10^4.7, 10^4.9, 10^5.1 and 10^5.3 K cm^-3 and the white contours at 10^5.5 and 10^5.7 K cm^-3. Lower right: goodness-of-fit with the same contours as in Fig. 18.
