DRAGONS
Data Reduction for Astronomy
from Gemini Observatory North and South

Current Status

The stable version is v3.0.0. DOI DRAGONS is distributed as a conda package, dragons, and it is included in the conda gemini stack.

Version 3.0.0 is recommended for the reduction of imaging data from Gemini's current facility instruments: GMOS, NIRI, Flamingos-2, and GSAOI.

There is now basic GMOS longslit support in DRAGONS to use only for quicklook purposes. To reduce Gemini spectroscopy data for science purposes, please continue to use the Gemini IRAF package.

To install DRAGONS:

$ conda create -n dragons python=3.7 dragons stsci

You might need to add two relevant conda channels if you haven't already:

$ conda config --add channels http://ssb.stsci.edu/astroconda
$ conda config --add channels http://astroconda.gemini.edu/public

A list of changes since 2.1.1. can be found in the Change Logs.


What is DRAGONS

DRAGONS is a platform for the reduction and processing of astronomical data. The DRAGONS meta-package includes an infrastructure for automation of the processes and algorithms for processing of astronomical data, with focus on the reduction of Gemini data.


Documentation

Documentation on DRAGONS v3.0 is available on "readthedocs" at:

There your will find manuals for Astrodata and the Recipe System, and hands-on tutorials on reducing Gemini imaging data with DRAGONS.

Gemini users with imaging data to reduce should pick the tutorial discussing the reduction of data from the appropriate instrument.

Software developers should start with the Astrodata and Recipe System manuals.
