Definition 4.10. Let $S$ be an oriented $3$-manifold diffeomorphic to $S^{3}$. For any point $p\in S\setminus L$, we consider $L$ as a link in the $3$-ball $S\setminus\{p\}$ and denote by $\pi\colon T(S,L)\to S\setminus L$ the bundle of bigraded abelian groups, whose fiber at the point $p\in S\setminus L$ is $\mathrm{KhR}_{N}(S\setminus\{p\},L)$ as defined in Definition 4.4.
