Data Reduction Pipelines for GRACES

GRACES, Gemini’s shared access to ESPaDOnS, the Canada-France-Hawaii optical spectrograph, now has two working pipelines for data reduction. OPERA, developed at CFHT, runs on all Gemini and CFHT data and the reduced spectra are delivered to PIs via the Gemini Observatory Archive. DRAGRACES is an easy-to-use IDL script that delivers a quick extraction. The latest version of OPERA is not yet public, but DRAGRACES can be accessed from the Gemini Data Reduction forum here.
