Dear Fazel

all variables in the stat file (http://amas.web.psi.ch/opal/Documentation/2021.1/Manual.html#sec.opalt.opalt-output)

are given in the co-moving frame, i.e. relative to the bunch centroid. The same it true when using the h5 file, 

as pointed out by Arnau. 

A good pointer is maybe the example of a rf photo injector that you can find

here https://gitlab.psi.ch/OPAL/src/-/wikis/Examples/RFPhotoInjector .

Let me know if you have more questions. 

Cheers Andy

Dear

I have problem with coordination system in OPAL code .

firstly I want to describe my project: I am designing a linear acccelerators that in this linac each cell and cavity are independent from each other and I introduce electric field and phase for each gap . so I want to get phase space for this accelerator . unfortunately I have problem with the coordination .

how can I get the {x,y,z} in the curvilinear system?

best regards
