Volvox Aureus - 632.8nm Measured scattering matrix elements F11 and -F12/F11 as functions of scattering angle theta (in degrees), corresponding to curves presented in Volten H, De Haan JF, Hovenier JW, Vassen W, Schreurs R, Dekker A, Hoogenboom HJ, Charlton F, Wouts R, Laboratory measurements of angular distributions of light scattered by phytoplankton and silt, Limnology and Oceanography, 43, 1180-1197 (1998). The experimental errors are also given. F11 is scaled to the scattering function of San Diego Harbour at a scattering angle of 90 degrees (SDH90).
