SMC843MHZ - Small Magellanic Cloud MOST 843-MHz Source Catalog

Overview

This table contains a new catalog of radio-continuum sources in the field of the Small Magellanic Cloud (SMC). This catalog contains 1689 radio-continuum sources detected at 843 MHz (lambda = 36 cm) from a radio survey of 36 square degrees containing the SMC (Turtle et al. 1998, PASA, 15, 280) conducted using the Molonglo Observatory Synthesis Telescope (MOST). These observations had a beam size of ~ 45 arcseconds and an rms noise of 0.7 mJy/beam. The MIRIAD task 'imsad' was used to detect sources in the 36-cm images, 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.

Provenance

This table was created by the HEASARC in September 2014 based on CDS Catalog J_other/Ser/183.103/ file tablea3.dat.

Parameters

Name
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.

RA
The Right Ascension of the 843-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.

Dec
The Declination of the 843-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.

LII
The Galactic Longitude of the 843-MHz radio source.

BII
The Galactic Latitude of the 843-MHz radio source.

Int_Flux_843_MHz
The integrated flux density of the 843-MHz radio source, in mJy.
