However, only triples contributions ε i jk are calculated if at least two of the three orbital pairs i j, ik and jk are considered as strong pairs according to the threshold τ CutPairs . Therefore, the semicanonical triples correction is indirectly affected by the pair selection threshold τ ∆ CutPairs . Additionally, we introduce a pair selection threshold τ ∆ CutTriples to reduce the number of triples contributions which are then only calculated if at least two of the three pairs are strong pairs and simultaneously fulfill Eq. ( ) for the given τ ∆ CutTriples .
