Model calculations of the excitation of the v = 1 and v = 2 J = 1–0 SiO maser transitions. The number of maser photons emitted as a function of the gas density is shown.The molecular excitation model includes the effects of the line overlap between the ro-vibrational lines ν2 = 0,127,5 –ν2 = 1,116,6 of para-H2O and v = 1, J = 0–v = 2, J = 1 of 28SiO.
