Hello! every SPIS user.
I’m beginner of SPIS. I’m on studying hall thruster plumes.
Whenever I add new empty characteristics of an ion species in SPIS, their id are -1 by default. (for example, In SPT100_300V_2mg device, I added f(energy) for Xe+ ion and id of f(energy) is -1) I wonder whether or not I should change the id in order to consider the effect of input value(f(energy)) and how to change id if it is needed.
