basis_id: int

Zero-based loop-momentum-basis identifier on the representative graph.

channel_id

Property · read-only
#
channel_id: Optional[int]

Effective multichannel identifier, or None when this basis is not sampled.

edge_ids

Property · read-only
#
edge_ids: list[int]

Edge identifiers whose momenta form the basis.
