Comparison of the estimated fluxes, desorption rates, and desorption efficiencies of CH3OH and CO species induced by IR and UV photons.
| Interstellar flux (photons cm−2 s−1 ) | Rate (molecules photon−1) | Estimated efficiency (molecules cm−2 s−1 ) | ||
|---|---|---|---|---|
| CO | IR | >3 × 109 (a) | ≲(1.1 ± 0.3) × 10−8(c) | ~3.3 × 101 |
| UV | ~1 × 104(b) | ~(0.14–8.9) × 10−2(d) | ~(1.4–89) × 101 | |
| CH3OH | IR | >4 × 108 (a) | ≲(3 ± 1) × 10−8(c) | ~1.2 × 101 |
| UV | ~1 × 104(b) | ~1 × 10−5(e) | ~1.0 × 10−1 |
