Molecular shielding and self-shielding factors in PRODIMO

Effect(0) Formula / Reference Flag
Self-sh. H2 → H2 Draine & Bertoldi (1996, Eq. (37)) Default
Self-sh. CO → CO Kamp & Bertoldi (2000) Default
Self-sh. C → C Default
Li et al. (2013), see footnote 1 Default
Self-sh. i → i(1) under v-integral Self_shielding

sh. H2 → CO Kamp & Bertoldi (2000, Eq. (23)) Default
sh. H2 → C Kamp & Bertoldi (2000, Eq. (8)) Default
sh. H2 → all(2) as H2 → C, but for λ < 1100 Å(4) H2_shielding
sh. C → H2, CO for λ < 1100 Å(4) Default
sh. C → all(2) for λ < 1100 Å(4) C_shielding

Notes. (0): Self-shielding is abbreviated as ‘self-sh.’ and shielding as ‘sh.’.(1): For all molecules ì without explicit self-shielding treatment;(2) : for all target molecules without explicit shielding treatment;(3) : constant : shielding factor applied under the v-integral for λ < 1100 Å;(5) : contains the H2 → N2 shielding, see also Visser et al. (2009).
