We first review the VFZ construction and interpolation methods which have been published elsewhere (Section 2.1). We describe tools to examine 5DOF results, including dimensionality reduction (Section 2.2) and techniques for estimating spatial correlation lengths (Section 2.3) and methods to visualize paths through the 5DOF space (Section 2.4). Finally, we describe literature datasets used in this work (Section 2.5).
