Illustration of line broadening and bisector modification by rotation. The black solid line shows an artificial line profile with a straight (but inclined) bisector (black dashed curve). The coloured curves were obtained by convolving the black curve with a (rigid-body) rotation profile of different width, simulating different velocities. Note that the bisectors (dashed curves) are modified by the convolution although the rotation profile is perfectly axis-symmetric.
