Abstract:
To complement the study of transient phenomena and to assist
subsequent observations in the mid-infrared, we extract point source
photometry from archival mosaics of nearby galaxies with high star
formation rates within 4 Mpc.
Point spread function photometry was performed on sources detected in
both Spitzer IRAC 3.6um and 4.5um bands at greater than 3σ above
background. These data were then supplemented by aperture photometry
in the IRAC 5.8um and 8.0um bands conducted at the positions of the
shorter wavelength sources. For sources with no detected object in the
longer wavelengths, we estimated magnitude limits based on the local
sky background.
Description:
We present a catalog of point sources from Spitzer mosaics of NGC 55,
NGC 253, NGC 2366, NGC 4214, NGC5253. We detect a total of 20159
sources in these five fields.
