figure 8(a):

The plotted curves are derived from the model given in the text. The code to generate the model is in the figure 4 folder. the parameters for the model are in the figure 3 folder.


figure 8(b):

The plotted curve is derived from the same model as (a). See above for information on the model.

There are two data folders, 8D etalon map and 9D etalon map. The datasets in each folder have the same form.

Each file in the folders has the form:

temperature (C)	photon counts (on)	photon counts (off)	power (mW)

Each file is taken at a different microwave frequency.


Calibration:

The temperature column referes to the temperature of the etalon and is realted to frequency through the calibration:

f = a1 + a2 T + a3 T^2 + a4 T^3

where f is the frequency and T is the temeprature. The coefficeint a1, a2, a3, a4 are found in file "etalon_calibration_parameters.csv" in the figure 4 folder.



Processing:

points where the laser power was greater than 1% of the average laser power are discarded.

the difference between the photon counts on and photon counts off columns are taken. The data is binned into 1 GHz bins

The data is fitted with a sum of three lorentzians.

The amplitude of the lowest frequency lorentzian is extracted as a function of microwave frequency for the two datasets. 

The ratio of these amplitudes is taken and plotted in figure 8.

the processing code is included in the subfolder in the Mathematica files

The plotting code is included in the code for the model in the figure 4 folder.
