A global NPDF analysis of the combined charged-lepton DIS, DY and neutrino DIS data finds a tension between the nuclear correction factors in nA DIS and ℓA DIS. We explore possible sources of this tension by comparing the input PDFs used by different nuclear global fitting groups, and also compute ratios of experimental observables which (largely) minimize any theoretical bias. We also show comparisons with recent nPDF determinations. This work helps to isolate the sources of possible tensions in the extracted nuclear corrections.
