Table 1: Observational conditions for 2867 Steins. The exposure time (exp) is the same for each of the four images obtained at the four different $\lambda /2$ retarder plate positions, while nset represents the number of repetitions of the full polarimetric sequences. Data on the position angle of the scattering plane ( $\phi$ ), on the phase angle ( $\alpha$ ), on the heliocentric (r) and geocentric ( $\Delta$ ) distances of Steins have been taken from the JPL ephemeris service (http://ssd.jpl.nasa.gov/cgi-bin/eph).
