Excitation temperature of p-HO 111−000, p-HO 202−111 for the envelope (upper) and the p-H2O 211−202, p-H2O 202−111 for the outflow (lower) assuming H2O column densities of N(H2O) = 1 × 1014 cm-2 and N(H2O) = 5 × 1013 cm-2 and source sizes of 4″ and 30″ for the envelope and the outflow, respectively as a function of kinetic temperature and H2 density calculated with RADEX (Non-LTE, large velocity gradient code). The gray areas indicate the derived Tex of envelope and outflow from the LTE rotation diagram analysis.
