  We demonstrate that the electronic bandstructure extracted from
quasi-particle interference spectroscopy [Nat. Phys. 9, 468 (2013)] and the
theoretically computed form of the superconducting gaps [Proc. Nat. Acad. Sci.
111, 11663 (2014)] can be used to understand the $dI/dV$ lineshape measured in
the normal and superconducting state of CeCoIn$_5$ [Nat. Phys. 9, 474 92103)].
In particular, the $dI/dV$ lineshape, and the spatial structure of
defect-induced impurity states, reflects the existence of multiple
superconducting gaps of $d_{x^2-y^2}$-symmetry. These results strongly support
a recently proposed microscopic origin of the unconventional superconducting
state.
