The recently published Gaia DR3 catalog of 181327 spectroscopic binaries (SB)includes the Keplerian elements of each orbit but not the measured radialvelocities (RVs) and their epochs. Instead, the catalog lists a few parametersthat characterize the robustness of each solution. In this work, we use twoexternal sources to validate the orbits - 17563 LAMOST DR6 and 6018 GALAH DR3stars with measured RVs that have Gaia-SB orbits. We compare the expected RVs,based on the Gaia orbits, with the LAMOST and GALAH measurements. Finding someorbits that are inconsistent with these measurements, we constructed a functionthat estimates the probability of each of the Gaia orbits to be correct, usingthe published robust parameters. We devise a clean but still very large GaiaSB1 sample of 91740 orbits. The sample differs from the parent sample by theabsence of - physically unlikely and hence presumably spurious - short-periodbinaries with high eccentricity. The clean SB1 sample offers the prospect ofthorough statistical studies of the binary population after carefully modelingof the remaining selection effects. At a first look, two possible featuresemerge from the clean sample - a paucity of short-period binaries with low-massprimaries, which might be a result of some observational bias, and a sub-sampleof main-sequence binaries on circular orbits, probable evidence forcircularization processes.
