MCCS stores calibration solutions in the ``ArtefactRepository`` with the ``.npy`` extension.
Each solution consists of 2048 values (4 flattened complex numbers per antenna), and the path to the
solution is stored in a PostgreSQL database together with metadata about the solution.

As it stands (09/12/2024), the PostgreSQL database schema is:
