The narrow-band impedance for each cavity consists of several resonators of the form (1), the parameters for which are given in Tab. 4.

Since the modes are so narrow, it is possible that the
precise value chosen for the mode frequency would cause the frequency
where a line in the bunch spectrum overlaps the cavity mode to fall
somewhere far away from the peak. Thus, in actual calculations, I
reduce the Q for each cavity mode (where necessary) to insure that
the values for their associated multibunch growth rates will be at
least 90% of their maximum possible values. Then, to account for
this 90% factor, the are increased by a factor of
1/0.9.
The cavities have an average 
-function of 200 m, and there are
three of these cavities [5].
