 ### Evaluation benchmark
 
 This benchmark tests how long it takes to evaluate a single point in the PSF model. This may seem contrived, but we expect performance to scale directly from this measure: if it takes 1 microsecond to evaluate a single point, it should take ~1 second to evaluate a 1000x1000 image, with speedups potentially from multithreading or SIMD loop evaluation.
