Minimum time step in Geant4-DNA chemistry

Hello, Is the minimum time step in TimeStepAction.cc of chem2 the same as literature?

This is the minimum time step in chem2.

This is the minimum time step in literature.(Karamitros, Mathieu, et al. “Diffusion-controlled reactions modeling in Geant4-DNA.” Journal of Computational Physics 274 (2014): 841-882.)

Dear,

This is chosen by users and their compromise between time consuming and precision. It is not the same also with different LETs

Thank you all. It helped a lot !
