Map of the signed squashing factor, signed log Q, computed at 3 R_⊙. The helmet streamer- heliospheric current sheet (HCS) is aligned in and out of the POS. Strong arcs at ±30° (±0.5 sin latitude) from the Sun equator indicate the signature of the large-scale pseudostreamers. The wind along the field lines rooted in the northern and southern coronal holes extensions spans the zone ±30° from the equator.
