WebJan 28, 2009 · A simple relation between dichroic extinction, color excess, CP, and LP is derived. The observed correlation between the Stokes parameters and the color excess agrees with the derived relation, and suggests a major contribution of dichroic extinction to the production of CP in this region, indicating the wide existence of aligned grains. Webplained by dichroic extinction. Lucas et al. (2005) showed that strong circular polarization can occur with extinction, if grains are small dielectric par-ticles. Buschermohle et al.
