The systems are classified into detached and overcontact configurations, followed by the identification of starspot signatures within both morphological classes. The classification was performed using a hierarchical computer-vision pipeline based on a fine-tuned ResNet-18 convolutional neural network trained on synthetic light curves generated with the ELISa code. The phase-folded Gaia G-band light curves are represented as 3-channel 128×128 pixel images encoding the flux distribution, its polar transformation, and the flux gradient. A tailored augmentation scheme calibrated to the Gaia cadence distribution was applied to reduce the synthetic-to-real domain gap (in prep). Because the morphological classification is based on single-passband Gaia G photometry alone, overcontact and ellipsoidal systems cannot be reliably distinguished. Therefore, systems with orbital periods P > 3 d initially classified as overcontact are explicitly reassigned as "ellipsoidal", since such long-period overcontact configurations are physically unlikely for main-sequence stars.Parimucha, S. and all, in prep.https://skvo.science.upjs.sk/upjs_gaia_eb/q/upjs_eb_cone/infoCatalogResearchIsServedByPavol Jozef Šafárik University Archive TAP servicePavol Jozef Šafárik University Archive TAP servicehttps://skvo.science.upjs.sk/upjs_gaia_eb/q/upjs_eb_cone/scs.xml?GETapplication/x-votable+xmlRARight Ascension (ICRS decimal)degpos.eq.rarealDECDeclination (ICRS decimal)degpos.eq.decrealSRSearch radiusdegrealsource_idGaia DR3 identifiermeta.id;meta.mainintegermain_classdetached, overcontact or Eellispsoidalmeta.code.classcharspot_classPresence of spotsmeta.code.classcharresponseformatFile format requested for output.meta.code.mimecharmaxrecMaximum number of records returned.
