Summary of solar wind streams for encounters 1 and 2, along with their identification numbers. All streams in encounter 1 (except E1S10) are from the same equatorial coronal hole. The period between E1S9 and E1S10 was ignored, as this is a heliospheric current sheet crossing (Szabo et al. 2020). Encounter 2 streams were picked according to the Rouillard et al. (2020) classification of non and streamer belt solar wind. A more detailed summary of these streams can be found in Table A.1. The top panels for both encounters show B_R multiplied by the radial distance to the Sun squared. This is an attempt to remove the first order variation in B_R, normalising the switchback amplitude with distance.
