"MIPSGAL'' is a survey of the Galactic plane at 24 and 70 microns using the Multiband Imaging Photometer for Spitzer (MIPS) onboard the Spitzer Space Telescope. The survey covers 220 square degrees of the inner Galactic plane spanning, -63 < l < 63 with a latitude range of |b| < 1 (excluding a region around the Galactic center). We describe the details of the 24 micron point source extraction method, including modifications to the default parameters in the MOsaicking and Point source EXtraction (MOPEX) package and the quality assurance tests we employ. Test runs show that we can reliably extract sources with fluxes in the range 1-1000 mJy with signal-to-noise ratios above 3. The results of the point source extraction are being compiled into a catalog that will be available to the general astronomical community. We present preliminary results on the content for selected MIPSGAL subfields such as source density, confusion limits, background complexity, and comparisons with other infrared plane surveys.
This work is based on observations made with the Spitzer Space Telescope, which is operated by the Jet Propulsion Laboratory, California Institute of Technology under a contract with NASA. Support for this work was provided by NASA through an award issued by JPL/Caltech.
