This directory contains the catalog of eclipsing binary stars detected
during the OGLE-II microlensing search in the Large Magellanic Cloud.

The directory structure is as follows:

README               -- this file

E.table.gz	     -- list of 2580 detected eclipsing binary stars (gzipped).
		        The columns are: number in the Catalog, Field, star ID,
		        RA(2000), DEC(2000), x, y coordinates in the reference
		        fts image, P(days), T_0 (HJD-245000), I_dia mag at
		        maximum, depth of the primary eclipse (I_dia magnitude),
		        phase of the secondary eclipse, depth of the secondary 
			eclipse (I_dia magnitude), I, V, B mag at maximum (from
		        standard OGLE-II photometry), eclipsing binary type,
		        overlapping star (0 if none).
		        Magic number -99.99 for secondary eclipse parameters
		        and for color columns means "no data".

EA_selected.table.gz -- list of 39 well detached binary systems well suited
		        for distance determination. Selection critera were:
		        I_dia < 16 mag, depth of the secondary eclipse > 0.2
		        mag. The columns are as above.
		        Please note that there are in fact 36 stars because 3
		        of them were detected in overlapping neighboring
		        fields (gzipped).

subdirectory fcharts  -- finding charts of individual objects; gzipped  
                         Postscript version. The file name is: object_id.ps.gz

subdirectory phot     -- photometry of individual objects:

    subdirectory Idia -- photometry in the I_dia band
    subdirectory I    -- photometry in the I-band (standard OGLE-II photometry)
    subdirectory V    -- photometry in the V-band (standard OGLE-II photometry)
    subdirectory B    -- photometry in the B-band (standard OGLE-II photometry)

                         The file name is object_id.dat.gz in each of these
                         subdirectories, except Idia, where file name is
                         object_id.dat. Each file contains 3 columns:
                         Hel JD, magnitude, error.


lmc_sc1.table	      -- Table with data for eclipsing stars in the field
		         LMC_SC1. The columns are the same as in E.table,
		         described above.

lmc_sc1.X.ps.gz	      -- Postscript version of the catalog of eclipsing
		         stars of the field LMC_SC1. X stands for page
		         number. Each page contains 28 stars' plots.

Any presentation of the scientific analysis or usage of the data from
the catalog of eclipsing stars in the LMC should cite the appropriate
OGLE paper(s).
