AB: Phase-sensitive holography has been used extensively to study solar subsurface mass flows. To date though, the ingression-egression correlation phases measured using phase-sensitive holography data have never been inverted. We present an inversion procedure, based on Born-approximation sensitivity functions and the MCD algorithm, for estimating subsurface flows from phase-sensitive holography measurements. We present some simple validation tests and example flow maps resulting from inversions of SOHO/MDI data.
