The obtained images were shifted back to the initial horizontal sample position with the help of the logged
shifts. We applied a simple filtered back projection for the reconstruction. In order to virtually increase the temporal
resolution of our measurement, we sorted the images in such a way that more than 8 reconstructions of the
sample could be computed. As the total measurement time was 37 hours and 8 minutes we decided to compute
v = 147 reconstructions providing a time resolution of 13.4 minutes for each reconstruction. In order to achieve
this, a reconstruction was performed on the images i * N − n)/v to i * (N − n)/v + n with i = 0, 1, ..., v. These image
subsets were further sorted so that the first image in each subset corresponded to ϕ = 0 in order to assure that the
reconstructions were intrinsically registered.
