11 ^(b)	CO + H + O₂	10	3 × 10¹²	7 × 10¹²	4 × 10¹²	–	–	14 400

Notes. Fluxes are calculated by the Hertz–Knudsen equation except for the H/D flux. ^(a) Fluxes adjusted during deposition in order to achieve the desired RAIR integrated band area ratio between H₂CO and H₂O. ^(b) H and D atoms are produced by the MWAS. Experiments 1–5 and 9 utilize the HABS.
