Displacement between the spacecraft’s coordinates and the source region’s coordinates. The magnetic connection of a fast (blue) and slow (red) solar wind package are shown in the reference frame of the spacecraft. The bending of the field lines below the source surface causes the magnetic displacement, the rotation of the Sun during the travel time from the source surface to the spacecraft causes the ballistic displacement. A solar wind package starts at the time t_ps at the photosphere, reaches the source surface at t_ss and is measured at t_sc by the spacecraft. The colored dashed lines indicate the magnetic connection between spacecraft and the solar wind’s sources.
