Spitzer Catalog of $7$ Galaxies

Khan et al. 2015(b)

Abstract:

We present Spitzer IRAC $3.6-8\,\micron$ and MIPS $24\,\micron$ point-source catalogs for seven galaxies: NGC$6822$, M$33$, NGC$300$, NGC$2403$, M$81$, NGC$0247$, and NGC$7793$. The catalogs contain a total of $\sim300,000$ sources and were created by dual-band selection of sources with $>3\sigma$ detections at both $3.6\,\micron$ and $4.5\,\micron$. The source lists become incomplete near $m_{3.6}=m_{4.5}\simeq18$. We complement the $3.6\,\micron$ and $4.5\,\micron$ fluxes with $5.8\,\micron$, $8.0\,\micron$ and $24\,\micron$ 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.
