Catalogue and photometry of eclipsing binary stars in the bar of the LMC
obtained from observations in two colours made during 1991-92 by the
French EROS project.

Note: Transformations between EROS B and R magnitudes (Be and Re), and
Johnson B and V magnitudes (Bj and Vj), and Cousins R magnitude (Rc).
The transformations and the r.m.s. deviations of a single measure, sigma, are:
Bj = Be + 0.46(Be - Re) sigma = 0.08 mag
Vj = Be - 0.47(Be - Re) sigma = 0.07 mag
Rc = Re + 0.07(Be - Re) sigma = 0.04 mag
(Bj - Vj) = 0.92(Be - Re) sigma = 0.10 mag
(Vj - Rc) = 0.49(Be - Re) sigma = 0.02 mag
(Bj - Rc) = 1.37(Be - Re) sigma = 0.08 mag

starting at 10001 (eclipsing binaries)
6- 7 I2 --- CCD Number of the detector on which the star fell
9- 13 I5 arcsec x Harvard (x,y) coordinates of the star,
accurate to about 3 arcsec (1)
15- 18 I4 arcsec y Harvard (x,y) coordinates of the star
accurate to about 3 arcsec (1)

39- 42 F4.1 arcsec DEs Declination J2000.0 (accurate to 0.2-0.3 arcsec)
44- 55 F12.4 d To(p) The heliocentric Julian date of the designated
primary minimum and its uncertainty. Where one
eclipse is clearly deeper, it has been taken as
the primary minimum. For some stars neither
minimum is clearly deeper and the eclipse
designated as primary is more or less arbitrary
57- 61 F5.4 d e_To(p) rms uncertainty on To(p)
63- 69 F7.4 d P Period of the system
71- 76 F6.4 d e_P rms uncertainty on P
78- 83 F6.2 -- dTo(p)/dP []? A partial derivative indicating how much
To(p) is affected by errors in P, where this is
significant.
85- 89 F5.2 --- Be(max) Approximate Be magnitudes at maximum light
91- 95 F5.2 --- Re(max) []? Approximate Re magnitude at maximum light
97-107 A11 --- Rem Remarks: The section of the printed paper in
which remarks are made about individual stars
