Comparison between the density and temperature evolutions as predicted by the Paris-Durham shock model (coloured curves) for initial pre-shock densities of 6 × 104 and 3 ×105 cm−3 and initial temperatures of 10 and 20 K with the densities and temperatures estimated with the RADEX analysis of the SO2 emission towards various SiO peaks (diamonds; see Table 3).
