Wind at 1 AU. Upper panels: bulk speed V_sw (lower plot) and correlation coefficient at 1 h scale C_vb (upper plot). The dashed red box marks the main portion of the Alfvénic slow wind stream. Lower panels: zoom of the time interval showing the scatter plots of θ_BR vs. T_∥ (upper panel) and θ_BR vs. T_⊥ (lower panel). The panels also show the value of the linear correlation coefficient between T components and θ_BR.
