  1. Most parameters are maintained throughout all computer experiments. Deviations from these parameters are listed in the respective experiment description. The value νm = − 1 in location-indexed experiments relates to self-motion. For D = 2 spatial dimensions, νself = − 2/D = − 1 yields a uniform prior distribution (see Supplementary Note 2, Section 1.3).
