  • FSRQs exhibit higher ratios of γ-ray to sub- 
  millimeter luminosity than BL Lacs (Figure 5), 
  but all objects inhabit a region of parameter 
  space suggesting transitions between states dur- 
  ing ﬂaring epochs.

  sample of objects for which we can perform this type of 
  analysis will increase and provide better limits on our 
  results. To understand the physical relevance of these 
  results, however, it is important to be able to distin- 
  guish between the diﬀerence in variability between BL
