GLEAM-X. Galactic plane
Listed in IVOA Registry (Virtual Observatory)
We present the third data release for the Galactic and Extragalactic All-Sky Murchison Widefield Array eXtended (GLEAM-X) survey, covering ~3800deg^2^ of the southern Galactic Plane (GP) with 233{deg}<l<44{deg} and |b|<11{deg} across a frequency range of 72-231 MHz divided into 20 sub-bands.
Description
GLEAM-X observations were taken using the "extended" Phase-ii configuration of the Murchison Widefield Array (MWA), which features baselines ranging from approximately 12m to 5km.
This configuration limits sensitivity to the diffuse structure of the GP, with an angular resolution range of about 45" to 2'. To achieve lower noise levels while being sensitive to a wide range of spatial scales (45"-15{deg}), we combined these observations with the previous Galactic and Extragalactic All-Sky Murchison Widefield Array (GLEAM) survey. For the area covered, we provide images spanning the whole frequency range.

A wide-band image over 170-231MHz, with RMS noise of ~3-6mJy/beam and source position accuracy within 1arcsec, is then used to perform source-finding, which yields 98207 elements measured across 20x7.68MHz frequency bands. The catalogue is 90% complete at 50mJy within 233{deg}<l<324{deg} and at 125mJy in 290{deg}<l<44{deg}, while it is 99.3% reliable overall. All the images and the catalogue are available online for download.
