hera_coupling

Python package for modeling and mitigating antenna-to-antenna mutual coupling in HERA visibility data.

Features

• Coupling Parameter Storage: Store coupling parameters in a UVMutualCoupling object with metadata (antpos, freqs, pols, times).
• Forward & Inverse Coupling: Perform both forward coupling and inverse decoupling operations, with optional first-order and multi-path corrections.
• HDF5 Read/Write: Read/write coupling parameters to HDF5 files via UVMutualCoupling.write_coupling and UVMutualCoupling.write_coupling.
• Multiple Data Format Support: Support for both hera_cal.datacontainer.DataContainer and numpy.ndarray
