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 +03o 18 m 20 s (MG1) and +02o 05 m 00 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.
