OPAL writes two kind of data:
- statistical data (.stat) such as rms beam sizes, rms emittances, energy, energy spread and much more, in ASCCI files, following the SDDS convention.
- phase space particle data is saved in the H5Hut (.h5) format which follows the general HDF5 conventions.
The statistical data can be conveniently plotted with gnuplot, as shown in the example section Cyclotron. For the h5 data we provide a root based plotting utility H5root. H5root is part of the binary package(/OPAL/wiki/TracIni#ctclotron1)
