Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.

First and foremost, The ProcName you are questioning is:
e.g. it is the name of the process that limited this current step.
G4Scintillation is a so called G4VRestDiscreteProcess and it is StronglyForced but its GetMeanFreePath and GetMeanLifeTime return DBL_MAX. This means, that as a process it will always be considered but it will not limit the step either in space or in time. Therefore, I do not understand why you get "Scintillation" instead of "Decay" in this line:
> 119 -8.52 351 9.01e+03 0 0 0 3.41e+03 physical_box_TEST Scintillation
If I find time, I'll debug this and try to understand it.
The G4Cerenkov process can, in some cases depending on user input, limit the step. In those cases you should see Cerenkov written in the SteppingVerbose. In most cases, another process will have limited the step and that process' name will appear. This doesn't mean that no Cerenkov photons were produced, only that it wasn't the Cerenkov process that limited the step.
The optical photons are not called 'Cerenkov' when they are propagated, nor are they called 'Scintillation'; regardless of how they have been produced their name is 'opticalphoton'.
