Notes. (a) Exposure time for each image in sec, (b) number of exposures used to obtain polarimetric parameters, (c) median heliocentric distance in au, (d) median geocentric distance in au, (e) median solar phase angle in deg,(f) position angle of the scattering plane in deg. The web-based JPL Horizons system (http://ssd.jpl.nasa.gov/?horizons) was used to obtain these quantities.
