GPI Data Pipeline Developer’s Guide

This document describes the internal workings of the GPI pipeline, and provides information on how to maintain, modify, and enhance it. It also tells you how to improve this documentation.

Warning

Compared to the other GPI pipeline docs, this is currently pretty rough - please treat this document as a work in progress!

This document assumes readers are already familiar with the content in the Installation & Configuration and User’s Guide sections.

See the development credits page for a list of GPI instrument team and Gemini staff members who have contributed to this project.
