Attached are the transfer function measurements of the FSS taken yesterday afternoon. The first two plots are taken with the common gain at 16 dB and fast gain of 22 dB. The second measurement (C16F22-2) I think was affected by the modecleaner trying to acquire lock, which might explain the notch-like feature just past 200 kHz. The UGF in both measurements is about 195 kHz. The third measurement, taken with a common gain of 20 dB and a fast gain of 22 dB is, I suspect, also affected by the modecleaner trying to acquire lock. Jason/Peter
