Notes.
Nucleus effective radius. See references in Combi et al. (2019) and Sect. A.3. For spacecraft and radar data, the error was assumed to be insignificant.
D/H in water. References in the review of Bockelée-Morvan et al. (2015), except for 67P (Altwegg et al. 2015), C/1996B2 (this work), and 46P (this work).
Water production rate at perihelion distance. From SWAN measurements (Combi et al. 2019), except for 1P (Feldman et al. 1997), 9P (Biver et al. 2007), 10P (Biver et al. 2012), and 81P (de Val-Borro et al. 2010). See Sect. A.3.
