The spat (symbol sp), from the Latin spatium ("space"), is a unit of solid angle. 1 spat is equal to 4π steradians or approximately 41253 square degrees of solid angle (sequence in the OEIS). Thus it is the solid angle subtended by a complete sphere at its center. (Wikipedia).

Edward Ionides: Island filters for inference on metapopulation dynamics
Low-dimensional compartment models for biological systems can be fitted to time series data using Monte Carlo particle filter methods. As dimension increases, for example when analyzing a collection of spatially coupled populations, particle filter methods rapidly degenerate. We show that
