 Notes: 
$V_{\rm crit}$ is the critical shock velocity below which J~shocks cease to exist (Eq.~(\ref{Eq-Vcrit})).
The initial core size distribution is a MRN over [100$-$3000~\AA] (see Sect.~\ref{PreshockDist}). 
When ranges are given, the lower limit corresponds to pure vaporisation with negligible erosion \citep[sputtering yields from][]{M00}, while the upper limit corresponds to the total of vaporisation and erosion with the \cite{T94} sputtering yields. We assume $b=1$, as per Eq.~(2), unless specified.
