\caption{\label{cloud-numbers}Number of CN radicals within the impact
  cloud and the derived number of parent molecules released by the
  impact. The values derived from spectra in different directions are
  given, assuming a spherically symmetric coma, respectively. $t-t_0$ gives
  the time since impact. $N_{\rm CN}$ corresponds to the total number CN
  molecules in the cloud, $N_{\rm p}$ is the  number of parent
  molecules, most likely HCN, derived from Eq.~(\ref{integrate}). All values are given in [10$^{29}$ molecules].}
