资源简介:
We present images and catalogues generated from the GLEAM-X survey, as described by Hurley-Walker et al. 2022b. The sky area covered is 4h < RA < 13h, -32.7deg < Dec < -20.7deg. We processed twenty frequency bands sampling 72--231\,MHz, with a resolution of 2'-45'$, and produced a wideband source-finding image across 170--231\,MHz with a root-mean-square noise of 1.27 +/- 0.15 mJy/beam. For each frequency, we supply here a map, estimates of the background and RMS noise, and a FITS file describing the point spread function, with four slices (restoring beam major and minor axes, position angle, and "blur" relative to perfect ionospheric conditions). Additionally, for the wideband image, we supply a cube with estimates of the complenetess at different flux density levels. The catalogue derived from the source-finding image contains 78,967 components and 317 columns.
