. Next: FSRQs Up: THE DEEP X-RAY RADIO Previous: Redshift Distribution . DXRBS' unique combination of a dual X-ray/radio survey method and high sensitivity has opened up important, large new regions of parameter space for both blazar sub-classes, within which a large fraction of our sample (nearly 50%) lie. This section is devoted to discussing these discoveries and their impact upon our understanding of the blazar class. љ . FSRQs . BL Lacs . Paolo Padovani . 1/5/1998
