Abstract:
    A set of 442 eclipsing binaries was selected from the GCVS catalog
    (Kholopov et al., 2003) that had declination <0°, minimum
    magnitude brighter than 13.0, and no published times of minima later
    than JD 2440000 available through the NASA ADS service. An automated
    web-based data gathering application was developed to retrieve and
    display data from the ASAS-3 database (Pojmanski, 2002, Cat.
    J/AcA/48/35>). A search radius of 45 arcsec was used when
    selecting candidate stars.
