124 CHAPTER 6: Physical Conditions in PDRs around Planetary NebulaeFigure 6.4–. Comparisonof the atomicfine structure linefluxes and the incidentflux densityof the oxygen- andcarbon-rich PNe withthe theoretical PDRmodels of Kaufmanet al. (1999) andW. Latter as reportedin Fong et al. (2001)respectively. <strong>The</strong>error in G 0 is approximatelyof the sizeof the plotted symbols.Note that theoxygen-rich PN Mz 3is not plotted becauseit lies outside themodel predictions forG 0. <strong>The</strong> intensitiesof the oxygen linesfor Mz 3 (the carbonline is not observed)are also higher thanthose predicted by themodels.
6.7. Physical conditions of the PDRs 125Figure 6.5–. Comparison of the O-rich model by Kaufman et al. (1999) (dashed and solid lines) withthe observational points (triangles).Figure 6.6–. Same as in Fig. 6.5 but comparing the C-rich model of W. Latter as reported in Fonget al. (2001) with the observational points (diamonds).
