Optimizing the accuracy of D measurements for single trajectories. Using longer traces improves the estimate of D, lowering ρ. Fixing the positional uncertainty σ (dashed line) in the MSD fit reduces in the relative error compared to fitting it (continuous line). Each point is the average ρ obtained from 100 simulated traces with length as indicated in the legend and D = 1 μm2/s
