Notes. The label of the feature, is indicated by its ID; t0 is the initial time at which each feature was tracked; Δϕ1 is the variation in the longitude of the PSP spacecraft during the tracking of the specific feature; ϕ2 and δ2 are the derived longitude and latitude, respectively; and v0 and r0 are the initial velocity and position of the feature. The last column represents the group in which the different features belong (see Sect. 4.2). In blue we show the results obtained with the fitting method of Braga & Vourlidas (2021), while in red we show the results from the fitting method of Liewer et al. (2020) (see Appendix A for more details).
