+=== Objectives ===
+Identifying Stellar Motions associating different Spiral Arm Scenarios
+=== Results ===
+Line of sight velocity of an axisymmetric distribution as function of galactic longitude:
+{{:tests:discs:vlos_helio_axisym.jpeg?200|}}
+{{:tests:discs:vlos_helio_axisym_in.jpeg?200|}}
+Residual l.o.s. velocity of an axisymetric distribution as function of galactic longitude:
+{{:tests:discs:vlos_res_axisym.jpeg?200|}}
+Substracted rotation curve:
+{{:tests:discs:rotcurv_axisym.pdf|}}
+-What we see is the velocity dispersion (no non-axisymmetric structures present in the model)
+-The asymmetry could be a consequence of the asymmetrical drift (it needs to be tested).
