Abstract

This work makes available a further 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 . Unlike previous GLEAM data releases, we used multi-scale uc(CLEAN) to better deconvolve large-scale galactic structure. For the galactic longitude ranges , , we provide a compact source catalogue of 22 037 components selected from a 60-MHz bandwidth image centred at 200 MHz, with RMS noise and position accuracy better than 2 arcsec. The catalogue has a completeness of 50% at , and a reliability of 99.86%. It covers galactic latitudes towards the galactic centre and for other regions, and is available from Vizier; images covering for all longitudes are made available on the GLEAM Virtual Observatory (VO).server and SkyView.
