this dataset is an emission spectrum taken using a fabry perot etalon. the excitation energy is fixed and the etalon is scanned by varying its temperature.
As in previous datset we recorded this with and without a microwave field.

the file AM04_norm_004 has 4 columns
temperature (C)	
photon counts (on)	
photon counts (off)	
power (mW)

the temperature (T) column is converted to a frequency (f) using the calibration f= x - 4.56 T +0.0621 T^2 - 0.000909 T^3 where x is adjusted such that f=0 corresponds to the peak in the counts off spectrum.
The calibration is svaed in this folder as a Wolfram function for use in the notebook.

the data is processed as follows:
the T column is converted to frequency using the calibration above
Any datapoints where the laser power is more than 2% of the mean are discarded.
There are mulitple measurements for each T, these are averaged.

The data was fitted using a lorentzian lineshape to guide the eye.
