Line profile variability for three strong Mn ii lines in the primary HgMn star: λ4756 (black triangles), λ4765 (red squares), λ4327 (blue circles). Statistical moments are plotted as a function of orbital phase: m0 = equivalent width, m1 = radial velocity, m2 = line width, m3 = asymmetry, m4 = kurtosis. Units are km s^-1 in the first (top) three panels, while m4 and m5 are dimensionless.
