[181.08] Point Sources and Source Subtracted Images in a Spitzer/IRAC Survey of the Galactic Center

S. Ramirez (IPAC/Caltech), S. Stolovy (SSC), R. G. Arendt (SSAI/GSFC), A. Cotera (SETI), D. Gezari (GSFC), J. Karr (SSC), C. Law (Northwestern Univ.), H. Moseley (GSFC), K. Sellgren (OSU), H. A. Smith, H. A. Smith (CfA), F. Yusef-Zadeh (Northwestern Univ.)

We present a discussion of the point source extraction procedure on \it{Spitzer Space Telescope}/IRAC observations of the central 280 x 210 pc (2 x 1.5 degrees) of the Galaxy. Measurements of the fluxes of point sources using PRF fitting and aperture photometry at 3.6, 4.5, 5.8 and 8.0 microns are presented, together with their distribution with galactic latitude and longitude. Source subtracted mosaics are shown to assess the quality of the flux measurements and its effects at studying the extended structure present in the field. Finally, we present preliminary colors of point sources in the Survey.
