To determine if the thermoelastic or the ablative regime %This affirmation  is dominant, we can look at the displacements patterns, which is different between the two regimes \cite{Davies_1993}. As the thermoelastic regime acts mainly as local dipolar forces parallel to the surface, the medium stretches locally parallel to confirmed by  the surface, resulting in observation of  a weak displacement \textit{outside} the medium along Z axis, disk of paler color of the same size  ascalculated previously.
