Abstract:
We present a catalog of point sources in the field of M83. Sources
were first cataloged that were found in both Spitzer IRAC 3.6-micron
and 4.5-micron images. These were then supplemented with 5.8 and
8.0-micron photometry. Ground-based near-IR photometry in J and
Ks-bands were extracted from imaging from the FourStar camera on the
Baade Magellan Telescope at Las Campanas Observatory. Optical
photometry was extracted from Hubble Space Telescope Wide Field Camera
3 observations of seven fields covering much of the bright disk region
of M83.
Description:
We extracted the mosaic image of M83 from the Local Volume Legacy
Survey (LVL, Dale et al., 2009ApJ...703..517D 2009ApJ...703..517D, Cat. J/ApJ/703/517) in
all four of the IRAC bands. The final images analyzed here cover an
area of 15' x15' with a pixel scale of 0.75arcsec/pix centered on the
nucleus of M83 (J2000.0:RA=13:37:00.9,DE=-29:51:56).
Observations of M83 were made in J and Ks with the FourStar
instrument attached to the 6.5m Baade Magellan Telescope at Las
Campanas Observatory on UT date 2014 Jan. 2.
Blair et al. (2014ApJ...788...55B 2014ApJ...788...55B, Cat. J/ApJ/788/55) studied
supernova remnants in M83 with seven fields of Hubble Space Telescope
(HST) Wide Field Camera 3 (WFC3) observations in multiple bandpasses.
Two fields come from the Early Release Science Program (ID 11360; R.
O'Connell, PI) with the remaining five coming from the cycle 19 HST
General Observer program 12513 (W. Blair, PI). These seven fields
cover the majority of the bright disk region of M83. We
specifically used the imaging and photometry in the F336W (Johnson U),
F438W (Johnson B), F555W (Johnson V) or F547M (Stroemgren y, easily
converted to Johnson V), and F814W (Johnson I) bands.
