Normalized cross helicity σ_c vs. normalized residual energy σ_r for structures with a high magnetic helicity (|σ_m|≥ 0.7) identified in the third orbit. We note that there is a lack of plasma data during the periods from 2019 August 31 to 2019 September 18, as well as between 2019 August 20 and 2019 August 21. Left panel: the scatter circles are colored according to the date. Right panel: the points are colored according to the radial distance to the Sun. The dashed-dotted circle represents . The magenta rectangular box represents the region that likely contains flux rope structures with a low value of normalized cross helicity|σ_c|≤ 0.3 and a highly negative residual energy σ_r ≤−0.5.
