SRC Detuning Convention
The SRC detuning is set in
Optics.SRM.Tunephase. The current gwinc convention is for the detuning to be 0 for RSE and pi/2 for SR. To my knowledge, this is the opposite of the convention used everywhere else where RSE is pi/2 and SR is 0. With RSE, the carrier picks up a 90 deg phase shift traveling one-way in the SRC. So I propose we change it so that
Optics.SRM.Tunephase is pi/2 for RSE and 0 for SR.
