Abstract

We present Spitzer IRAC 3.6-8{mu}m and Multiband Imaging Photometer 24{mu}m 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 >3{sigma} detections at both 3.6 and 4.5{mu}m. The source lists become significantly incomplete near m_3.6_=m_4.5~=18. We complement the 3.6 and 4.5{mu}m fluxes with 5.8, 8.0, and 24{mu}m fluxes or 3{sigma} 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.
