    • Comparison of methods for generation of absolute reflectance factor values for bidirectional reflectance-distribution function studies 

      Feng, Xiaofan; Schott, John; Gallagher, Timothy (Optical Society of America (OSA), 1993-03)
      Currently, spectrophotometric standard reference materials are calibrated only by using the illumination and viewing geometries recommended by the Commission Internationale de l'Eclairage, and for some geometries the ...
    • A spectropolarimetric atlas of Seyfert 1 galaxies 

      Smith, James; Young, Stuart; Robinson, Andrew; Corbett, Elizabeth; Giannuzo, Ester; Axon, David; Hough, James (Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2002-09-27)
      We present optical spectropolarimetry of the nuclei of 36 Seyfert 1 galaxies, obtained with the William Herschel and the Anglo–Australian Telescopes from 1996 to 1999. In 20 of these, the optical emission from the active ...
