Notes. Col (1): Observed frequency in GHz. Col (2): Integrated flux density in mJy.

^a:

The GLEAM flux density refers to the wide band from 139 to 170 MHz and from 170 to 231 MHz.

^b:

The WISH value is reported without an uncertainty in the catalog; the error on the WALLABY measurements takes the statistical uncertainty from the Gaussian fit and a 5% of systematic error as reported by Glowacki et al. (2023) into account. Col (3): Reference survey. Col (4): Angular resolution in arcsec. Col (5): Date of the observation.
