Each pair of columns shows the LOS velocity stratification and the corresponding synthesized Stokes V profiles. The temperature of the model used in the synthesis is hotter than the HSRA reference atmosphere. The magnetic field vector has a constant 1 kG intensity and zero degrees in inclination and azimuth. The first column shows a LOS velocity jump of 5 km s^-1 that moves from the top to the bottom of the photospheric layers. The second column shows the resulting Stokes V profiles. The third column shows an opposite jump, with higher velocities at lower heights. The Stokes V profiles obtained from this velocity configuration are plotted in the fourth column. The last column shows the synthetic profiles when the LOS velocity stratification has a Gaussian perturbation, as shown in the fifth column.
