Hα and Na i D2 average LOS velocities (), standard deviation (σ), and number of points (#) used for the statistics.
|[km s-1]||[km s-1]||points|
|Na i D2||−0.023||0.606|
|Na i D2||+ 0.010||0.588|
|Na i D2||+ 0.042||0.622|
Notes. Maps 5–7 in Fig. 3 where used for the spine statistics. The average quiet-Sun velocity was computed using maps 1–3 (excluding pixels belonging to the filament and bright points seen in Na i D2).
