The Evolution of the Centimeter-Submillimeter Spectrum of 3C 345 during Outburst
(1996-07-01)
Monitoring data between 375 and 4.8 GHz are presented for the blazar 3C 345 between 1989 and 1995, during which period the source flared. The multifrequency light curves are used to construct snap-shot spectra that span ...
3C 279 Multiwavelength Monitoring II : The Ground-based Campaign
(1996-03-01)
The optically violently variable quasar 3C 279 was monitored simultaneously from radio to y-ray frequencies in 1992 December-1993 January. We report a detailed study of the ground-based results from radio to optical ...
