Dear all,
this question is a bit basic, however I would like to double check if my understanding is correct.

Using PoG 0.2.1 I want to simulate LWFA in a plasma channel of let say 3 mm long. I want my gas profile to be uniform in transverse direction. In the longitudinal direction I want my gas profile to have a plateau and super-gaussain up/down ramps -- exactly how it is specified in gasConfig.param file. Am I correct that to achieve it the only thing I need to do is to fix numerical values for a length of ramps and plateau to fit my overall plasma length?
Please note that in the speciesIntizialation.param file this profile is already pointed a source of particles.

Thanks a lot for you support,
Danila.
