Inversion Codes

Stokes inversion techniques represent the most sophisticated way to interpret spectropolarimetric observations. Europe has a long tradition in the development of inversion codes. As a service to the community, this page offers the possibility to download some popular codes used in Europe and elsewhere. Their application to Hinode/SP measurements should be straightforward.
