Remarks:
The second part of this study was published by Bernhard (2010).

Presented are the details for thirty eight 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 a eclipsing binary in variability catalogues.

The astrometric positions were derived from the MACHO data base and were improved using Carlsberg Meridian Catalog 14 (CMC14 2006), 2MASS (Skrutskie et al. 2006) and Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE 2008) if available. The Macho R magnitudes were calculated from the given instrumental R magnitudes using the formula given in Alcock et al. (1999). The programme Period04 (University of Vienna) was used for the data analysis.

Acknowledgements: This paper utilizes public domain data obtained by the MACHO Project, jointly funded by the US Department of Energy through the University of California, Lawrence Livermore National Laboratory under contract No. W-7405-Eng-48, by the National Science Foundation through the Center for Particle Astrophysics of the University of California under cooperative agreement AST-8809616, and by the Mount Stromlo and Siding Spring Observatory, part of the Australian National University. The application TOPCAT (http://www.starlink.ac.uk/topcat) was used for the access of the data. Catalogue data served by the VizieR service of the CDS, Strasbourg, was used in this analysis. It is a pleasure to thank John Greaves for providing a list of likely eclipsing binaries from the Scutum MACHO Galactic Bulge fields 301-303 and for further helpful suggestions and comments.
