The MG1 and MG2 MOTESS-GNAT surveys were conducted as 48-arcmin wide scan-mode CCD imaging surveys of selected areas of the sky in an efficient and highly successful asteroid search program. The images were reduced photometrically as a test of a prototype of a longitudinally distributed network of photometric scan-mode telescopes for the Global Network of Astronomical Telescopes, Inc. (GNAT). The MG1 and MG2 surveys, which are unfiltered, are centered at declinations +03\circ 18\rm m 20\rm s (MG1) and +02\circ 05\rm m 00\rm s (MG2), respectively. Although the source data were originally intended for astrometric use, they nonetheless have yielded a great deal of useful stellar brightness data. As such, they serve as excellent test-beds for both future GNAT photometry surveys and as valuable sources of new scientific discovery and analysis. To assist in defining some of the possible serendipitous programs using the MG1 and MG2 Surveys, we present in this poster an analysis of the photometric precisions that are attained in these data sets.

This effort is supported in part by the National Aeronautics and Space Administration through the NASA Astrobiology Institute under Cooperative Agreement No. CAN-02-OSS-02 issued through the Office of Space Science. The NSO and the NOAO are operated by AURA for the NSF.
