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

Anonymous 4 months ago • updated by Archive Science Group 4 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.

Thank you for reaching out to us.

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