Abstract

Abstract This work makes available a further $2\,860~\text{deg}^2$ of the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey, covering half of the accessible galactic plane, across 20 frequency bands sampling 72–231 MHz, with resolution $4\,\text{arcmin}-2\,\text{arcmin}$ . Unlike previous GLEAM data releases, we used multi-scale CLEAN to better deconvolve large-scale galactic structure. For the galactic longitude ranges $345^∘ < l < 67^∘$ , $180^∘ < l < 240^∘$ , we provide a compact source catalogue of 22 037 components selected from a 60-MHz bandwidth image centred at 200 MHz, with RMS noise $≈10-20\,\text{mJy}\,\text{beam}^{-1}$ and position accuracy better than 2 arcsec. The catalogue has a completeness of 50% at ${≈}120\,\text{mJy}$ , and a reliability of 99.86%. It covers galactic latitudes $1^∘≤|b|≤10^∘$ towards the galactic centre and $|b|≤10^∘$ for other regions, and is available from Vizier; images covering $|b|≤10^∘$ for all longitudes are made available on the GLEAM Virtual Observatory (VO).server and SkyView.
