The light curve files have the following 3-column format:

· Column 1 - the Heliocentric Julian date (HJD), minus 2400000

· Column 2 – normalized r-band magnitude

· Column 3 – magnitude uncertainty

Plots of the catalog light curves:

Both the phased light-curve/model plot (black dots: normalized observed magnitudes; blue curve: MECI model) and the model residual plot (below) of each EB in the catalog are shown here. The listed periods (P) are in units of days.

I. Eccentric [N=34]: EBs with unequally-spaced eclipses (PDF) (postscript)

II. Circular [N=290]: EBs with equally-spaced but distinct eclipses (PDF) (postscript)

III. Ambiguous-unequal* [N=103]: EBs with undetected secondary eclipses (PDF) (postscript)

IV. Ambiguous-equal* [N=103]: EB with equally-spaced and indistinguishable eclipses (PDF) (postscript)

V. Inverted** [N=23]: detached EBs that are not successfully modeled by MECI (PDF) (postscript)

VI. Roche-lobe-filling** [N=318]: non-detached EBs that are filling at least one Roche-lobe (PDF) (postscript)

VII. Unclassified Abnormal*** [N=20]: EBs with atypical out-of-eclipse distortions (PDF1 PDF2) (postscript1 postscript2)

* These two groups contain the same EBs, where each binary in group IV is assumed to have twice the orbital period of the respective entry in group III. These systems are only counted once.

** The models of these EBs produce poor fits. We included them here for illustrative purposes only. We do not use their fitted parameters.

*** See Table 5 in paper for details. Note that all but five systems are modeled and classified in other groups.

Errata: [NEW]

1. In the AJ paper, the labels of the final three light curves in panel 3 of Figure 11 (Eccentric EBs) should be: T-Tau0-02487, T-Tau0-03916, T-UMa0-01822 (as written in Table 3). This error had been corrected in the astro-ph listing.

2. The catalog coordinates of T-Cas0-00524 are wrong. They should read:
RA = 00:52:43.013 Dec =+50:28:10.20 (J2000)
This target is a known Algol-type eclipsing binary, identified as V364 Cas (among other identifiers; see SIMBAD). Because it was matched up with a wrong 2MASS source, its listed colors and MECI analysis results are wrong as well. We are currently investigating the cause of this mismatch and checking to see if other targets were affected as well. We currently believe that the pipeline reduction error that caused this mismatch affected, at most, only a small number of light curves within the Cas0 field.
