Quality Control and
Data Processing

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 on the Paranal instrument page.

In April/May 2008, the old GIRAFFE CCD was been replaced by "Carreras", with much higher red sensitivity and reduced fringing in the red.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 is provided here.

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

All calibration data from GIRAFFE pass Quality Control Garching.

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