From the last plot:
- Subtracting the offset of 0.0095, the modulation depth were estimated to be 0.20 for 11MHz, 0.25 for 55MHz
- Carrier TEM00 1.0, 1st order 0.01, 2nd order 0.05, 3rd order 0.002, 4th order 0.004
==> mode matching ~93%, dominat higher order is the 2nd order (5%).
Eric: now we have the number for the mode matching. How much did the cavity round-trip loss be using this number?
