Notes. Col. 1: Project code. Col. 2: Observing frequency. Col. 3: Peak intensity of the MODELFIT core component and associated uncertainty. Col. 4: Post-fit rms of the MODELFIT residual map. Col. 5: Beam major axis. Col. 6: Beam minor axis. Col. 7: Resolution limit. Col. 8: Ratio between the core size and the resolution limit. Col. 9: Core brightness temperature and associated uncertainty. A lower limit is given when the core size is smaller than the resolution limit.
