  In this article, we derive and compute the sensitivity of measurements of
coupling between normal modes of oscillation in the Sun to underlying flows.
The theory is based on first-Born perturbation theory, and the analysis is
carried out using the formalism described by \citet{lavely92}. Albeit tedious,
we detail the derivation and compute the sensitivity of specific pairs of
coupled normal modes to anomalies in the interior. Indeed, these kernels are
critical for the accurate inference of convective flow amplitudes and
large-scale circulations in the solar interior. We resolve some inconsistencies
in the derivation of \citet{lavely92} and reformulate the fluid-continuity
condition. We also derive and compute sound-speed kernels, paving the way for
inverting for thermal anomalies alongside flows.
