Phase angle dependence of polarimetric color for 1999 JD₆ and size-dependent meteorites. The open red circles and solid lines represent data corresponding to 1999 JD₆. The polarimetric data of two meteorites, CO3-class NWA 4868 and CV3-class Allende, have been measured under deposited layer conditions in the laboratory (Hadamcik et al. 2011). The blue squares and cyan triangles adjacent to the dotted lines show a grain size of <50 μm and <200 μm for the NWA4868 meteorite, respectively. The orange crosses and dark green diamonds adjacent to the dashed lines denote <50 μm and <500 μm Allende meteorite particles, respectively.
