Notes. (a) Number of lines used for the determination of Q, which are in parentheses when individual lines are not clearly detected. (b)Where we assume that H2CO is produced in the coma by a distributed (H2COd) source and follows a Haser daughter species density profile with a parent-scale length of 8500 km.
