Interstellar extinction and polarimetric properties of the star HD 200775
Reddening and polarization are obtained and separated into intrinsic andinterstellar components for the Herbig Be star HD 200775, which issurrounded by the NGC 7023 reflection nebula. A reddening map based onstar counts is used to derive the relation between (C-13)O columndensity and extinction, and the maximum interstellar polarization isfound to be 0.88 percent at the maximum wavelength of 0.532 microns;this indicates that the size distribution of the particles in the cloudresponsible for the optical extinction and polarization is rathersimilar to that of the surrounding interstellar medium.
