\caption {\label{Param}Values for the parameters (other than grain mass) used in the modelling. $T_{\rm lim}$ is the temperature at which fragmentation occurs, 
$T_{\rm boil}$ the boiling point of the grains, $C_{\rm p}$ the specific heat, Mmass the molar mass, and Thermal Cond the thermal conductivity of the bulk meteoroid
(Meteor ELSL11).}
