Giraffe is part of the complex FLAMES spectroscopic facility installed at the Nasmyth A focus of UT2/Kueyen. FLAMES feeds the two spectrographs UVES and Giraffe simultaneously through fibre connections. Find more about the FLAMES facility here.

In April/May 2008, the old GIRAFFE CCD has been replaced by "Carreras", with much higher red sensitivity and reduced fringing in the red. It is an e2v 2-layer anti-reflection coated, deep-depletion CCD, with the same number of pixels (2048x4096) as the old CCD. More information provided here.

This section of the Data Processing and Quality Control web pages covers the FLAMES/Giraffe data. Find the FLAMES/UVES section here.

A general description of the FLAMES capabilities is also available.

All calibration data from Giraffe pass Data Flow Operations Garching.

Use the Giraffe archive web page to browse and download Giraffe raw data.
