J/A+AS/120/89 408MHz observations (Bondi+ 1996) ================================================================================ A 15 years monitoring program at 408 MHz Bondi M., Padrielli L., Fanti R., Ficarra A., Gregorini L., Mantovani F. =1996A&AS..120...89B (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Galaxies, radio Keywords: galaxies: active - quasars: general - radio continuum: galaxies Description: This is the second paper based on the 408MHz monitoring program with the East-West arm of the Bologna interferometer. The monitoring concerned 125 radio sources measured approximately once a month for 15 years. We present the summary of the variability analysis concerning all the sample and the monitoring data, not yet published, of the variable sources.
