Early science of GRACES: the Gemini Remote Access to CFHT ESPaDOnS Spectrograph
Lison Malo



The Gemini Remote Access to CFHT ESPaDOnS Spectrograph has achieved first lights of its experimental phase in May 2014. Last August, first science programs were observed using this 270m optical fiber link between CFHT and Gemini North telescope. GRACES achieved delivering spectra with a power resolution of 40,000 and 65,000 between 400 and 1050 nm. This project is a great example of a productive collaboration between two observatories on Maunakea that was successful due to the reciprocal involvement of the Gemini, CFHT, NRC Herzberg teams, and all the staff involved during the last decade. During this talk, I will review the project and the performances achieve during the first experimental phase and discuss how the OPERA pipeline was used to reduce the GRACES data and present some early science results.
