Notes. The W1, W2, and S1 are within the complex solar wind intervals observed by Wind and STA and are associated with CMEs and their source active regions mentioned in the column labeled “Event/Source”. The CMEs’ first arrival at the coronagraph is mentioned in the column “Time”, and their initial propagation direction, velocity, aspect ratio, angular width, and tilt are provided in the columns Dir, Speed, A, AW, and Tilt, respectively. This information was measured close to the origin (< 30Rs) reported by the previous studies Liu et al. (2024) (L) and Khuntia et al. (2025) (K).
