Table 3: Values of non-dissociative single ionization (photoionization) cross section, $\sigma _{\rm ph-i}$, and dissociative ionization (photodissociation) cross section, $\sigma _{\rm ph-d}$, of CH3OH as a function of photon energy. The estimated experimental error was 30%. The photoabsorption cross section ( $\sigma _{\rm ph-abs}$) from Ishii & Hitchcook (1988) is also shown.
