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. A “+” indicates that offset data have been taken into account.

(b)Where we assume that HNC is produced in the coma with a Haser parent scale length 2000 km. (c)Where we assume that CS is produced in the coma with a Haser parent scale length 2000 km. (d)Where we assume that H2CO is produced in the coma with a Haser parent scale length 1700 km.
