The run directories contain unformatted data files
either as data/proc0 (for 128x128x32_20kc_BDMSST93c_Oml)
or as data/proc0-3 (for 128x64_20kc_BDMSST93_wind10a), or as bb.sav
just for the magnetic field components in the other directories.
They can be read directly with the corresponding idl routines
that are in the directory (run_directories/run_idl) together with
those delivered with the Pencil Code (https://github.com/pencil-code).
