                            CategoryTheory.ShortComplex.LeftHomologyMapData (S.mapNatTrans τ) (h.map F) (h.map G)

Given a natural transformation τ : F ⟶ G between functors C ⥤ D which preserve the left homology of a short complex S, and a left homology data for S, this is the left homology map data for the morphism S.mapNatTrans τ obtained by evaluating τ.
