- class openmc.DelayedGroupFilter(bins, filter_id=None)¶
Bins fission events based on the produced neutron precursor groups.
bins (iterable of int) – The delayed neutron precursor groups. For example, ENDF/B-VII.1 uses 6 precursor groups so a tally with all groups will have bins = [1, 2, 3, 4, 5, 6].
filter_id (int) – Unique identifier for the filter
id (int) – Unique identifier for the filter
num_bins (Integral) – The number of filter bins
