Only the selected center band is centered. The untouched core factors combine with the retained center factors into the exact divisor

OAI.TwoPointCorrelations.centerBand_reindexline 147Source documentation
The removed-prime choice can be made first; the retained subset then runs through the complementary pool. No cardinal multiplicity is added.

OAI.TwoPointCorrelations.centerBand_reindex_retainedline 178Source documentation
The retained-prime product is the outer summation variable used in the analytic transfer. Removed and retained primes are disjoint exactly.
