Two-dimensional CCF(τ,v) showing the correlation coefficient of the He I λ5876 line segment light curves with the continuum light curve as functions of velocity and time delay (blue scale). Contours of the correlation coefficients are plotted at levels 0.0–0.9 every 0.05 (white lines). The green line shows the line profile of the mean spectrum.
