Notes. ζ2 values are calculated following the recent results of Bovino et al. (2020) and assuming three values of ℓ in Eq. (5). (a) Data and calculations from Giannetti et al. (2014). We assumed a constant [18 O]/[17O] = 4.16, as in Wouterloot et al. (2008). Values in boldface were taken from Csengeri et al. (2016).
