Subject: beam profiles 

Here are the new beam profiles after the faraday isolators. I am satisfied with the CCW profile, but the CW looks a bit crap. It is much more astigmatic, and I'm afraid that some diffractive effects near the output of the FI are tricking the fitting algorithm. We are going to re-profile the beam after the MMT, so we will verify that it is matched to the cavity mode and make adjustments if necessary.
