Summary and Future work
˙ We can reproduce a single  observed lcıs with a combination of quadrupolar B-field components and viewing angles

˙ But although in most cases this fit certainly exists, it is in general not unique: degeneracy and non-linear dependence on physical variables !

˙ Therefore,  it is difficult to reproduce variations observed in a single source

˙ Reduce the degeneracy:
a)learning more about the clustering of models

b)looking at the lcıs in different colour bands and/or line variations with spin pulse

               Þ Need to increase the grid of models!
