Stacked observing-block level 1D spectra are now added to the FLAMES/GIRAFFE stream

Published: 12 Feb 2019

All qualifying GIRAFFE Medusa data are now processed into stacked 1D spectra, whenever the observing block that created the raw products contains more than one SCIENCE exposure. Backwards processing of stacks for the historical part is also completed such that more than 360,000  1D spectra products are available as processed in-house products from the Archive Science portal. Single-exposure 1D spectra are also produced and can be found as associated ancillary files or as science products, if originating observing block contains a single exposure only.

The wavelength scale of these spectra products is in the heliocentric reference system. All stacked 1D spectra come with associated single exposure 1D spectra products, error estimates and signal-to-noise ratio per wavelength bin, and  sky spectra when available. The 1D spectra tagged "GIRAFFE_MEDUSA", can be queried and downloaded using the Archive Science portal.

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