Bold letters emphasize highest values at the given distance
Air particle velocities measured at same distances (⩾5 mm) but at different positions were compared using one-way repeated measures ANOVA (F-values given). Level for significance of difference is P_{corr.}⩽0.025. Values in a row that have same superscript letters did not differ significantly from each other (pairwise comparison: Tukey-test, P>0.05); n.s., not significant
