The GLEAM SGP year 1, year 2, and combined year 1 and 2 mosaics. The
year 1 data were taken almost entirely over the period August-November
2013 and the year 2 data were taken over the period August-December
2014. The exact dates of the observations are given in Table 1 of
Franzen et al. (2021). The combined year 1 and 2 mosaics have the best
sensitivity and should be used if you are not concerned about the
observing epoch.

In each case, a total of 17 mosaics are provided:
- a wide-band mosaic at 200-231 MHz
- 16 7.68-MHz sub-band mosaics spanning 103-231 MHz
The wide-band mosaic has the best sensitivity and resolution. The
sub-band mosaics provide additional spectral information.

The rms, background and local PSF maps associated with each mosaic are
provided in the tarball files.

# -------- GLEAM SGP catalogue  --------

1) GLEAM_SGP_catalogue.fits

The GLEAM SGP catalogue is based on the GLEAM SGP combined year 1 and
2 mosaics as well as additional GLEAM Exgal mosaics (Hurley-Walker et
al. 2017) below 100 MHz. The catalogue contains 108,851 source
components detected above 5 sigma in the GLEAM SGP wide-band mosaic
centred at 216 MHz. It includes the following information:
- the position, integrated flux density and shape of each source in
   the GLEAM SGP wide-band mosaic
- the integrated flux density and shape of each source in the 16 GLEAM
   SGP sub-band mosaics between 107 and 227 MHz
- the integrated flux density and shape of each source in the 4 GLEAM
   Exgal sub-band mosaics between 76 and 99 MHz
- the local PSF at the location of each source in the wide-band and
   sub-band mosaics
- the spectral index between 76 and 227 MHz measured from the sub-band
   flux densities
A description of the 313 columns of the catalogue can be found here;

2) completeness_maps.tgz

FITS cubes tracing the spatial variation of the completeness of the
GLEAM SGP catalogue at 216 MHz at various flux density levels:
- 15-50 mJy in steps of 2.5 mJy
- 55-100 mJy in steps of 5 mJy
- 120-300 mJy in steps of 20 mJy
Details on how the completeness maps were generated can be found in
section 4.3 of Franzen et al. (2021).
