The POVM_Mueller_Raw_Data folder contains all the raw data gathered during the experiment which was processed and analysed for the paper.

The folders within are named according to the data that was taken, either corresponding to Mueller measurements, Stokes measurements or stability data.

HWP_QWP_Mueller_Data contains Mueller measurements of half- and quarter-wave plates at different angles, taken either with the POVM system or using Stokes tomography. 
The relevant povm states to reconstruct the polarisation is also included.

Tilted_QWP contains Mueller measurements of a tilted QWP taken with the POVM system.

The Stability folders contain measurements of the orthogonal POVM states over either a 3 hour or 8 hour time period.
 
The raw data is in the form of png files corresponding to POVM measurements (a single png for each) or Stokes measurments (6 png files for each).
