Notes. (1) Taken from Asplund et al. (2009) and Wakelam & Herbst (2008). (2) Taken from Wakelam & Herbst (2008) and Navarro-Almaida et al. (2021). (3) As in the low-metal abundance case from Graedel et al. (1982) and Morton (1974). (4) We considered a depletion factor of 10 with respect to the sulphur cosmic elemental abundance of 1.5 × 10−5 to take into account the recent sulphur depletion results from Esplugues et al. (2022), Esplugues et al. (2023), and Fuente et al. (2023). (5) Taken from Neufeld et al. (2005). (6) Taken from Navarro-Almaida et al. (2021) and Jiménez-Serra et al. (2018). (7) Taken from Navarro-Almaida et al. (2021). (8) Taken from Wakelam et al. (2021).
