abstract
We present catalog of 26 121 visually inspected eclipsing binary stars identified in the Large Magellanic Cloud during the third phase of the Optical Gravitational Lensing Experiment. The sample is limited to the out-of-eclipse brightness I < 20 mag. The catalog consists mostly of detached eclipsing binaries - ellipsoidal variables were not included. For stars brighter than I = 18 mag the detection rate of eclipsing binaries is 0.5% and for all stars it falls to 0.2%. The absolute completeness of the whole catalog is about 15% assuming the occurence rate of EBs toward the LMC equal to 1.5%. Among thousands of regular eclipsing systems we distinguished a subclass of eclipsing binaries - transient eclipsing binaries (TEB) - presenting cycles of appearance and disappearance of eclipses due to the precession of their orbits.

The authors deliver a combined SBCR for stars below ~16 solar masses spanning V-Ks from -0.9 to 2.1 mag with 0.025 mag scatter, plus a separate O-star relation, and verify it on an M33 eclipsing binary.
