Gemini Data Reduction Software

Gemini offers data reduction software for its facility instruments. The Gemini IRAF package and the DRAGONS platform are the official data reduction software supported by Gemini.

For the next several years we will be transitioning from the IRAF platform to our new Python-based DRAGONS platform. As time goes by, more and more instruments and modes will be supported by DRAGONS. During this transition, it is possible that users will require both platforms depending on the data they have obtained.

  • Latest version of Gemini IRAF:  v1.15  (June 2022)
  • Latest version of DRAGONS:  v3.2.0  (April 2024)

Which platform should I use?

Gemini IRAF currently still support all the instruments and modes. However for any imaging data from current instruments,  DRAGONS should be used. DRAGONS currently support imaging data reduction, GMOS longslit spectroscopy (including nod&shuffle mode) and GHOST data reduction.
