Resumen
The Optical Gravitational Lensing Experiment (OGLE) produced as a by-product a catalog of ∼ 220,000 candidates to variable stars. The data were collected in the I band and consist of images and light curves. On the other hand, at the same epoch, the Two Micron All-Sky Survey (2MASS) covered the whole sky providing accurate positions and fluxes for ∼ 4.7×10^8 point sources in the J, H and K_S photometric bands. In this work, we present a systematics for the identification of eclipsing binaries in OGLE-II that have infrared counterparts in the 2MASS survey. To do this, we used the Principal Component Analysis as a selection tool.
