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.
