cds-question@unistra.frradio-sourcesphotometryOptical identifications have been sought for 304 radio sources from the declination -20{deg} region of the first Molonglo deep survey. Optical objects have been measured using the Palomar sky survey to an accuracy of 1 arcsec and magnitude estimates are to 0.4mag. Finding charts are given for all fields with optical objects within +/-2{sigma} of the radio position. Sixteen QSOs have been confirmed (details have been reported elsewhere) amongst the blue stellar-like objects and spectroscopy is complete to m_o_=19.5. The mean magnitude of the QSOs is 19.2 and the mean redshift is 1.34. A study of the background densities of objects indicates that about half of the remaining blue stellar-like objects are QSOs and about 80 per cent of the galaxies are associated with the radio emission. The QSOs are amongst the fainter and the bluer of the blue stellar-like objects. There is no evidence for any average offset between the radio and optical positions.1987MNRAS.227..607Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/227/607CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/16 : Molonglo Reference Catalogue of Radio Sources (Large+ 1991)J/ApJS/107/19 : MRC/1Jy Radio source survey.
