Correction to the article: Floer homology and splicing knot complements
  This note corrects the mistakes in the splicing formulas of the paper "Floer
homology and splicing knot complements". The mistakes are the result of the
incorrect assumption that for a knot $K$ inside a homology sphere $Y$, the
involution on the knot Floer homology of $K$ which corresponds to moving the
basepoints by one full twist around $K$ is trivial. The correction implicitly
involves considering the contribution from this (possibly non-trivial)
involution in a number of places.
