Synthetic images created by using different numbers and sizes of particles. a Synthetic images created by setting the number (N) and size (R pixels) of particles to (left) 200 and 10, (middle) 200 and 12, or (right) 150 and 10, respectively. b, c Curves of mean COR as a function of distance d when θ = 135 are shown for synthetic images with different b numbers (N) or c sizes (R pixels) of particles. Gray arrows indicate d converging to zero. d Exponential curves fitted to COR values as a function of d when θ = 135 are shown for actual Day 1 and Day 3 oocytes (n = 10 animals in each age group; orientation of the worms is 0°). e, f Exponential curves fitted to COR values as a function of d when θ = 135 are shown for synthetic images with different e numbers (N) or f sizes (R pixels) of particles
