****************************************************************
The folder 'faradayData' contains the raw data for figures 2-5.
****************************************************************

The data within this folder are structured as follows

The folder 'glassOnly' contains the raw data used to measure faraday rotation in an empty glass cuvette.

The folder 'oil+glass contains the raw data used to measure faraday rotation in a glass cuvette filled with oil.

In each of these two folders, there is a small plotting python script named plot.py

There are also several sub folders with numerical names. These numerical names correspond to wavelengths at which the raw data was collected, as described in the text.

Each of these sub folders contains raw data files with a naming convention as follows:

[data type]_[magnet turns]_[wavelength]_[dataset idintifier].data

where [data type] is one of 'o', for a cuvette containing oil, or 'g', for an empty glass cuvette.

for example, a data file entitled 

o_3_808_3.data

would correspond to data taken to determine the faraday effect of a glass cuvette containing oil, with the magnet positioned three full turns from the stop, using an 808 nm probe laser, and being the third data sets taken at this wavelength.

Three data sets were taken in every case, such that [dataset identifier] is always 1, 2 or 3.

***********************************************************
The folder 'magneticField' contains the data for figure A1.
***********************************************************

This folder contains the data used to calculate the magnetid field of the magnets at the various magnet positions. During the experiment, the magnet could be reliably returned to a certain magnetic field strength by screwing the magnets towards or away from eachother in their threaded mount.

This data contains the measured magnetic field data at each of the positions used, identified as being a number of 'turns' from the maximum possible field obtainable (when the magnets are touching the cuvette). This allows for a number of 'turns' to be converted directly into a known magnetic field.

This folder contains the raw data for the range of fields available, as well as a small plotting utility, which displays all the raw data.
