Time-traces from aLOG's 77133, 77268 and 77710 were used to deduce the systems parameters. Three types of measurements were acquired: without the squeezer beam, without the Filter Cavity, and with both. The data was normalized, therefore, we analyzed the value in decibels of quantum noise reduction compared to no squeezing rather than the PSD of the signal.

Budget module QuantumRelGamma was used for fiting.

To fit the measurements without the Filter Cavity, we assumed the Filter Cavity Mismatch parameter to be 1 (equivalent to ifo.Squeezer.Type = 'Freq Independent').

After inferring the quantum noise by adjusting the arm power and optical gain parameters, we then adjusted all other parameters, mainly focusing on phase, Filter Cavity detuning, injected squeezing, SEC detuning, and IFO-OMC mismatch.

The code was primarily based on Dhruva's interactive-sqz-main.
