Comparison between simulated results and mapped-back in-situ observation of the Ulysses spacecraft. The simulated results are represented by black scatters while the observed data are represented by green scatters in the first (speed) and second (density) row. The heliolatitude and heliolongitude of Ulysses are plotted in the third row. The start time of each Carrington rotation (CR) is marked at the top of the figure. The three intervals, i.e., before mid of CR 2069, between mid of CR 2069 and mid of CR 2075 and after CR 2075, are separated by the vertical dashed line.
