Eclipsing binary stars in the WWW interface to the catalog are sorted by type or by the field they are located in. Menu from the left frame switches between those two categories (three types: EA, EB, EW, and 11 OGLE-II fields in the SMC). When one of the types or one of the SMC fields is chosen, the table with stars and their basic parameters appears in the bottom right frame. Columns of the table are: number of the star in the catalog, OGLE-II field (in EA, EB or EW tables the name of the field points to the table with all eclipsing stars in a given field), name of the star, RA, DEC, x and y coordinates in the reference image, orbital period of the system, Heliocentric Julian Date for the primary maximum (T0-2450000), DIA I-band brightness in maximum, DIA I-band amplitude (depth of the primary minimum), phase of the secondary eclipse, its depth in the DIA I-band ("-" for phase and depth mean, that the secondary eclipse were not detected automatically, or detected incorrectly), I, V and B brightness at maximum, type of eclipsing star and notes with information on a counterpart star identified in overlaping field (field name given) and/or number of star in previous edition on the catalog (Udalski et.al 1998). Type of the eclipsing star may contain additional information about the object ("ecc" stands for stars with large eccentricity, "AP" for stars with possible large apsidal motion).

Tables with stars sorted by type are divided to contain 100 stars per page. Links to other pages are placed above and below the table.

The name of the star in the table is a link. When clicked, the selected star is presented in detail in the upper right frame. The frame contains main information about the star: number, field, name, period, DIA I-band light curve and a finding chart (part of the reference image). The size of the finding chart is 168 x 168 pixels, corresponding to 70 x 70 arcsec on the sky. North is up and East is to the left. Clicking the name in this window provides photometry of the star in the format: Heliocentric Julian Date, magnitude and magnitude error. Clicking with Shift key pressed allows to download the photometry file.

The entire distribution of the Catalog can be downloaded from the OGLE Internet archive. See README file there for details.
