Presented are the details for twenty eclipsing variables found from the Scutum MACHO Galactic Bulge fields 301-303 epoch photometry as publicly served via their new Virtual Observatory interface (Smillie 2009) and as downloaded and sourced via TOPCAT.
Each object was checked against the Strasbourg CDS Vizier service and the International Variable Star Index (http://www.aavso.org/vsx/) for pre-existence as an eclipsing binary in variability catalogues.
The astrometric positions were derived from the Carlsberg Meridian Catalog 14 (CMC14 2006) and 2MASS (Skrutskie et al. 2006) if available. The Macho R magnitudes were calculated from the instrumental R magnitudes using the formula given in Alcock et al. (1999). The programme AVE (GEA) was used for the data analysis.
