cds-question@unistra.frmagellanic-cloudseclipsing-binary-starsphotometryWe present a large sample of eclipsing binary stars detected in the Small Magellanic Cloud fields covering about 14 square degrees that have been monitored for eight years during the third phase of the OGLE survey. This is the largest set of such variables containing 6138 objects, of which 777 are contact and 5361 non-contact binaries. The estimated completeness of this sample is around 82%. We analyze the statistical properties of the sample and present selected interesting objects: 32 systems having eccentric orbit with visible apsidal motion, one Transient Eclipsing Binary, ten RS CVn type stars, 22 still unexplained Double-Periodic Variable stars, and 15 candidates for doubly eclipsing quadruple systems. Based on the OGLE-III proper motions, we classified 47 binaries from our sample as foreground Galactic stars. We also list candidates suitable for the SMC distance determination.2013AcA....63..323Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/63/323CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/48/563 : BVI photometry of OGLE SMC eclipsing binaries (Udalski+, 1998)J/AcA/48/147 : OGLE SMC BVI photometry (Udalski+ 1998)J/AcA/51/317 : OGLE DIA.
