cds-question@unistra.freclipsing-binary-starsastronomical-reference-materialsvisible-astronomytrigonometric-parallaxWide-band photometryinfrared-photometrystellar-radiiUsing a sample of 81 Galactic, detached eclipsing binary stars we investigated the global zero-point shift of their parallaxes with the Gaia Data Release 2 (DR2) parallaxes. The stars in the sample lay in a distance range of 0.04-2kpc from the Sun. The photometric parallaxes {omega}_Phot_ of the eclipsing binaries were determined by applying a number of empirical surface brightness-color (SBC) relations calibrated on optical-infrared colors. For each SBC relation we calculated the individual differences d{varpi}_i_=({varpi}_Gaia_-{varpi}_Phot_)_i_ and then we calculated unweighted and weighted means. As the sample covers the whole sky we interpret the weighted means as the global shifts of the Gaia DR2 parallaxes with respect to our eclipsing binary sample. Depending on the choice of the SBC relation the shifts vary from -0.094 to -0.025mas. The weighted mean of the zero-point shift from all colors and calibrations used is d{omega}=-0.054+/-0.024mas. However, the SBC relations based on (B-K) and (V-K) colors, which are the least reddening dependent and have the lowest intrinsic dispersions, give a zero-point shift of d{omega}=-0.031+/-0.011mas in full agreement with results obtained by Lindegren+ (2018A&A...616A...2L) and Arenou+ (2018A&A...616A..17A). Our result confirms the global shift of Gaia DR2 parallaxes of d{omega}=-0.029mas reported by the Gaia team, but we do not confirm the larger zero-point shift reported by a number of follow-up papers.2019ApJ...872...85Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/872/85CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/168 : Homogeneous Means in the UBV System (Mermilliod 1991)I/259 : The Tycho-2 Catalogue (Hog+ 2000)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)V/152 : The DEBCat detached eclipsing binary catalogue (Southworth, 2015)I/345 : Gaia DR2 (Gaia Collaboration, 2018)I/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer- Jones+, 2018)J/ApJ/469/355 : Teff, B-V and BC relation (Flower, 1996)J/A+A/324/137 : Eclipsing binaries with candidate CP stars (North+ 1997)J/AJ/119/1389 : The binary star FS Monocerotis (Lacy+, 2000)J/A+A/387/850 : Radial velocities of eclipsing binaries (Imbert, 2002)J/AJ/128/1340 : The eclipsing binary star V459 Cas (Lacy+, 2004)J/AJ/128/1840 : The eclipsing binary star MU Cas (Lacy+, 2004)J/AJ/128/1319 : New AY Cam Photometric Observations (Williamon+, 2004)J/MNRAS/363/529 : uvby, UBV & radial velocity of WW Aur (Southworth+, 2005)J/AJ/132/2489 : Light curves of HD 71636 in B and V (Henry+, 2006)J/AJ/131/2664 : Photometry and radial velocities of EY Cep (Lacy+, 2006)J/A+A/461/1065 : uvby diff. photom. of 4 EBs (Clausen+, 2007)J/ApJ/663/320 : IR-through-UV extinction curve (Fitzpatrick+, 2007)J/A+A/463/579 : Geneva photometry of HD 23642 (Groenewegen+, 2007)J/A+A/461/1077 : Radial velocities of DW Car (Southworth+, 2007)J/A+A/487/1095 : RVs of AD Boo, VZ Hya, WZ Oph (Clausen+, 2008)J/A+A/483/263 : BV light curve of V570 Per (Tomasella+, 2008)J/A+A/480/465 : V505 Per BV light curves (Tomasella+, 2008)J/MNRAS/400/969 : ASAS detached EB parameters (Helminiak+, 2009)J/AJ/137/507 : Light and velocity curves of VZ Cep (Torres+, 2009)J/AJ/138/1622 : Absolute properties of LV Her (Torres+, 2009)J/A+A/511/A22 : EW Ori differential uvby light curves (Clausen+, 2010)J/A+A/516/A42 : Spectral lines of BK Peg and BW Aqr (Clausen+, 2010)J/other/A+ARV/18.67 : Accurate masses and radii of normal stars (Torres+, 2010)J/AJ/142/185 : The eclipsing binary stars HY Vir (Lacy+, 2011)J/AJ/141/195 : BV light curves of FT Ori (Sabby+, 2011)J/ApJS/193/1 : UBVRIJHK color-temperature calibration (Worthey+, 2011)J/AJ/144/63 : Spectroscopic & photom. obs. of V335 Ser (Lacy+, 2012)J/AJ/143/129 : Photometric & Spectroscopic obs. of BF Dra (Lacy+, 2012)J/AJ/143/5 : uvby photometry and RVs of HD 74057 (Sowell+, 2012)J/A+A/540/A64 : uvby light curves of EF Aqr (Vos+, 2012)J/A+A/557/A119 : Eclipsing binary system LL Aquarii (Southworth, 2013)J/other/PASA/31.24 : Milky Way detached double-lined EB catalog (Eker+, 2014)J/ApJ/780/59 : The Araucaria project: EBs in SMC (Graczyk+, 2014)J/A+A/563/A120 : Y Cyg light curves and time of minima (Harmanec+, 2014)J/AJ/148/71 : Spectroscopy and photometry of V501 Her (Lacy+, 2014)J/AJ/147/148 : Spectroscopy and photometry of AP And (Lacy+, 2014)J/ApJ/797/31 : G+M eclipsing binary V530 Orionis photom.
