Research data supporting "True to size surface mapping with neutral helium atoms"

Simulated SHeM images and the associated 3D reconstructions and reconstruction errors that are presented in the associated publication. The contents of this data pack are split into: 1. A series of ray tracing simulation results that are provided in full, base simulation data of all the reconstructions presented in the paper are present. Those used for non-normal incidence with rotation are found with the 3D reconstructions rather than in the ray tracing results folder. 2. A selection of heliometric reconstructions. All the reconstructions that are directly presented in the paper are included. 3. Data on overall reconstruction accuracy that is used to produce the plots in the paper. All data is provided either in plain text or matlab `.mat` format. The provided `.stl` and `.png` files are for convinience, and replicate data stored in the `.mat` files.
