Notes. Subscript “d” has been added to the molecules for which a daughter Haser density profile is assumed with the parent scale length provided below.
(a)Number of lines used for the determination of Q, in parentheses the number of lines that are not individually detected.
(b)Where we assume that HNC is produced in the coma with a Haser parent scale length of 2000 km (Cordiner et al. 2017).
