SMC1400MHZ - Small Magellanic Cloud ATCA and Parkes 1400-MHz Source Catalog



This table contains a new catalog of radio-continuum sources in the field of the Small Magellanic Cloud (SMC). This catalog contains 1560 radio-continuum sources detected at 1400 MHz (lambda = 20 cm) from a set of new high-resolution radio-continuum mosaic images of the SMC created by combining observations from ATCA and Parkes (Wong et al. 2011, SerAJ, 182, 43). The 20 cm mosaic image (Fig. 2 in above reference)was created by combining data from ATCA project C1288 (Mao et al. 2008, ApJ, 688, 1029) with data obtained for a Parkes radio-continuum study of the SMC (Filipovic et al. 1997, A&AS, 121, 321). This image had a beam size of 17.8 x 12.2 arcseconds and an rms noise of 0.7 mJy/beam. The MIRIAD task 'imsad' was used to detect sources in the 20-cm image, requiring a fitted Gaussian flux density > 5 sigma (3.5 mJy). All sources were then visually examined to confirm that they were genuine point sources, excluding extended emission, bright side lobes, etc.

This table was created by the HEASARC in September 2014 based on CDS Catalog J_other/Ser/183.103/ file tablea2.dat.


The name of the radio source using the style recommended by the Dictionary Of Nomenclature of Celestial Objects, viz., the [WFC2011] prefix (for Wong, Filipovic, Crawford 2011) and the J2000.0 equatorial coordinates truncated to 1 second of time and 1 arcsecond in RA and Dec, respectively.

The Right Ascension of the 1400-MHz radio source in the selected equinox. his was given in J2000.0 equatorial coordinates to a precision of 0.1 seconds of time in the original table.

The Declination of the 1400-MHz radio source in the selected equinox. his was given in J2000.0 equatorial coordinates to a precision of 0.1 arcseconds in the original table.

The Galactic Longitude of the 1400-MHz radio source.

The Galactic Latitude of the 1400-MHz radio source.

The integrated flux density of the 1400-MHz radio source, in mJy.
