SubjetBuilderCfg()

SubjetBuilderCfg	(		flags,
			target_jets,
			output_container = None,
			ghost_association = 'GhostTruth',
			radius = 0.2,
			pt_min = 5000,
			link_name = None,
			count_name = None,
			name_suffix = '' )

Recluster ghost-associated constituents of a jet into small-R subjets.

Subjets above ``pt_min`` are written to their own container and linked back
from the parent jet.

Fails outright if the ghost association is missing from the jets.

Parameters
----------
target_jets : str
    Jet collection whose ghost constituents are reclustered.
output_container : str, optional
    Output subjet container. Defaults to
    ``<target_jets><ghost_association>Subjets``.
ghost_association : str
    Ghost-associated constituent links read off ``target_jets``.
radius : float
    Anti-kt clustering radius.
pt_min : float
    Minimum subjet pT in MeV.
link_name, count_name : str, optional
    Decorations written on ``target_jets``. Bare names, not prefixed.
