Relation between kG feature size and its internal mean micro turbulent velocity. The plus, star and diamond symbols indicate the log(τ) = 0, −0.8 and −2 layers respectively. The error bars denote the error in the mean. The black symbols refer to plage and the red to network areas. The dashed, solid, and dotted lines indicate the mean microturbulence in quiet Sun intergranular lanes at log(τ) = 0, −0.8 and −2, respectively. All the mean microturbulent velocities were calculated using ten logarithmic bins per decade of patch area.
