Abstract:
We present Spitzer IRAC 3.6-8µm and Multiband Imaging Photometer
24µm point-source catalogs for seven galaxies: NGC6822, M33,
NGC300, NGC2403, M81, NGC0247, and NGC7793. The catalogs contain a
total of ∼300000 sources and were created by dual-band selection of
sources with >3σ detections at both 3.6 and 4.5µm. The source
lists become significantly incomplete near m3.6=m_4.5~=18. We
complement the 3.6 and 4.5µm fluxes with 5.8, 8.0, and 24µm
fluxes or 3σ upper limits using a combination of PSF and
aperture photometry. This catalog is a resource as an archive for
studying mid-infrared transients and for planning observations with
the James Webb Space Telescope.
