MOLONGLO: catalogue of radio sources


Table name:     MOLONGLO 
Records:        12141
Spectral Band:  RADIO  
Kind of Object: Radio Sources
Coordinates:    B1950        



This catalogue lists 12141 discrete radio sources from a 408-MHz survey observations made with the Molonglo Radio Telescope. The survey covers 7.85 sterad of the sky defined by declination from +18.5 to -85.0 deg. and galactic latitude from -3 to +3 deg. The catalogue comprises celestial coordinates with standard error typically lying between 3 and 10 arcsec and 408-MHz flux densities with standard error typically lying between 4 and 10 per cent, down to the flux limit of 0.7 Jy. There are 7347 sources of listed flux density .ge. 1.00 Jy, at which level the catalogue is substantially complete. The reliability is believed to be better than 99.9 per cent.
