﹩{\rm{\Delta }}{\chi }^{2}﹩ value in the model parameter space T_ℓ and n for NGC 5033. At temperatures lower than 88 K (the maximum T_ℓ value for a 1σ contour plot), the model yields similar flux ratios. Molecules with temperature less than a sensitivity temperature T_s = 88 K have negligible contribution to ﹩{{\rm{H}}}_{2}﹩ rotational line flux in the galaxy NGC 5033.
