All spectra obtained with the spectrograph FLAMES/GIRAFFE in the MEDUSA mode from June 2005 till December 2014 are now published via the ESO archive as reduced data. The extracted, wavelength calibrated, one-dimensional spectra are in tabular FITS format, see the ESO science data products standard for a description of the data format and metadata information. Their wavelength scale is in the heliocentric reference system. All 1D-spectra come with error estimates and signal-to-noise ratio per wavelength bin. There are a number of files associated at download time to each spectrum, including sky spectra when available. The GIRAFFE_MEDUSA data collection will grow with time, with new reduced spectra being added with monthly cadence. FLAMES GIRAFFE spectra acquired before June 2005 will also soon be added to the collection. The 1D spectra tagged "GIRAFFE_MEDUSA", can be queried and downloaded using the Phase 3 generic query form that provides access to all Phase 3 data or the Phase 3 query form dedicated to spectral data with query parameters suited to harvest spectral data.

More details about the data can be found in the associated Phase 3 data release description for GIRAFFE_MEDUSA data.

Instructions on how to read and display 1D spectra in the FITS tabular format can be found in the 1d spectrum data format help page.
