Scatter plots of the velocities at which the 20% of the maximum line profile is attained at each side of the maximum emission (x- and y- axes respectively). The left and central plots correspond to the C iv line in the quiet Sun regions and in the proximities of the active regions; the rightmost scatter plot corresponds to the Ne viii line in the proximities of the active regions. The colour code represents the total flux radiance in a logarithmic scale. Blue correponds to the lowest values of the line radiance and red corresponds to the highest values.
