PICARD — a PIpeline for Combining and Analyzing Reduced Data

Version 1.0.0

User’s Guide


Picard is a facility for combining and analyzing reduced data, normally the output from the Orac-dr data reduction pipeline. This document describes an introduction to using Picard for processing instrument-independent data.
