GRACES
GRACES (Gemini Remote Access to CFHT ESPaDOnS Spectrograph) is a fiber feed from Gemini/GMOS to ESPaDOnS, the Canada-France-Hawaii Telescope optical spectrograph.
Data Reduction Pipelines for GRACES
There are now two working pipelines for data reduction.
(i) OPERA, developed at CFHT, runs on all Gemini/CFHT data and the reduced spectra are delivered to the PIs via the Gemini Observatory Archive.
(ii) DRAGRACES is an easy-to-use IDL script that delivers a quick extraction.
More information about both methods and a comparison between their deliverables can be found at the GRACES Data Reduction page. The latest version of OPERA is not yet public, but DRAGRACES can be accessed from the Gemini Data Reduction Forum
