Notes. All values are production rates with respect to the water production rates as presented in Table 3. For comet 9P/Tempel 1, the values in brackets are valid for assuming the water production rate according to Mumma et al. (2005). As no acceptable fit could be obtained with both reaction networks, the presented values must not be regarded as predictions of the abundances of these species.
