Detailed Description

Steers the loading of FSP particles.
This does NOT include RootInput, Geometry or anything required before loading FSPs,
the user has to add this himself (because it depends on the MC campaign and if you want
to use Belle or Belle II).

get_fsp_lists()

typing.List[str] get_fsp_lists

(

self

)

Returns a list of FSP particle lists which are used in the FEI.
This is used to create the RootOutput module.
