Description:
The catalogue lists 167 eclipsing binary stars in the Small Magellanic
Cloud detected in the database of time-series photometry for 400000
SMC stars acquired by the Microlensing Observations in Astrophysics
(MOA) project during 1997. Coordinates, ephemerides, magnitudes and
light curves are presented. Thirty-five systems are new detections.
The limiting magnitude is about 17.5. The majority of periods lie
within the range 0.4 to 20 days; 6 systems are possibly eccentric
while 14 are probably or certainly so. The majority of the
newly-identified systems lie in the outer regions of the SMC.
