Welcome to the SKA SDP Continuum Imaging Pipeline (CIMG) documentation!

The SKA SDP Continuum Imaging Pipeline (CIMG) uses the Prefect workflow engine to orchestrate a basic continuum imaging pipeline using WSClean. This is a work in progress and subject to frequent changes.

A flow chart of the pipeline is shown below (click to zoom).
