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

The `SKA SDP Continuum Imaging Pipeline (CIMG)
<https://gitlab.com/ska-telescope/sdp/science-pipeline-workflows/ska-sdp-cimg>`_ uses the `Prefect
<https://docs.prefect.io/v3/get-started>`_ workflow engine to orchestrate a basic continuum imaging
pipeline using `WSClean <https://wsclean.readthedocs.io/en/latest/>`_. This is a work in progress
and subject to frequent changes.

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