QUIESCENCE<br />
The next <strong>state</strong> is quiescence. It is not really clear whether it is a separate <strong>state</strong>, or simply a<br />
low-lum<strong>in</strong>osity version <strong>of</strong> the hard <strong>state</strong>. Quiescence is slight s<strong>of</strong>ter than quiescence, but<br />
appears still to be quite variable. Jets are still present at 10e-8 Ledd, follow<strong>in</strong>g the same<br />
radio/X-<strong>ray</strong> relations seen <strong>in</strong> the hard <strong>state</strong>.
