UVES Echelle products: corrections for barycentric or heliocen-tric motion

Anonymous 2 months ago updated by Archive Science Group 2 months ago 1

Hello, In the ESO Phase 3 Data Release Description (https://www.eso.org/rm/api/v1/public/releaseDescriptions/163) it is indicated (page 5) that "No corrections for barycentric or heliocentric motion have been applied.", but the information is in the header (HIERARCH.ESO.QC.VRAD.BARYCOR or HELICOR, in km/s).

In order to combine (e.g. average) different UVES spectra is it OK to use the header values for correcting manually barycentric or heliocentric motion before the combination of the spectra ? Is there a suggestion for this kind of operation ?

In any case, it is very nice to have these UVES spectra available. Thanks.

The heliocentric or barycentric correction provided in the header is suitable for general purposes. However, I cannot confirm its precision.
