000007204 520__ $$aCross-calibration between spectroscopic surveys is fundamental to anchor the analysis of millions stars on solid grounds. Nevertheless, 10 to 15 percent of a random sample of stars will appear as spectroscopic binaries, which can alter the atmospheric parameters derived from single-star analysis pipelines. This is why it is important to include a small sample of well-known spectroscopic binaries across spectroscopic surveys to assess the effect of binarity through different spectrographs at different resolutions and wavelength coverages, on the pipelines in charge of deriving the atmospheric parameters. Another interesting aspect of this cross-calibration will be the possibility to detect and characterize a few thousands of spectroscopic binaries from the cross-calibration sample (excluding the sample of well-known binaries), taking advantage of the cadence for free of each survey, that will provide enough epochs to constrain orbital parameters, once the zero-point of each spectrograph is well constrained.
