Approximate Extraction of Late-Time Returns via Morphological Component Analysis

no code implementations11 Aug 2022 Geoff Goehle, Benjamin Cowen, Thomas E. Blanford, J. Daniel Park, Daniel C. Brown

Under the framework of Morphological Component Analysis (MCA), we compare two separation models using the short-duration and long-duration responses as a proxy for early-time and late-time returns.
