192. source comment
. Comment on J0126-0123 . No detection: this object has been studied with the Molonglo telescope at 408 MHz (Schilizzi & McAdam 1975) as a source with a size between 2 and 5 . It is near an Abell cluster (Owen & Ledlow 1997). The data could be confused with a strong radio source (3C 40) identified with a pair of galaxies at z=0.018, 170" from our field center.
