Consecutive differences of the cone projection areas A_Δh1, 2 defined by Eq. (1) (blue line, top panel) and the percentage of the relative change in the dimming area inside the projection area for consecutive cones (green line, bottom panel) for the May 8, 2024, event. The vertical dashed line indicates the step (associated with a cone height of 0.81 R_sun, a width of 69.8°, and an inclination angle of 7.7°) where the consecutive differences (blue line) reach 5% of the maximum of the cone projection area and just before the increase in percentage of the relative change in the dimming area within the projections (green line).
