Figure 2: Polarization-phase dependence of E-type asteroids. Data for 44 Nysa and 64 Angelina are taken from Zellner & Gradie (1976), Cellino et al. (2005), Rosenbush et al. (2005), Fornasier et al. (2006). The continuous line shows the fitting of all data by the linear-exponential function proposed by Kaasalainen et al. (2003); the dashed line shows the linear fit to Steins' data. |

Figure 3: IRAS albedo versus polarimetric slope. Polarimetric data taken from Lupishko & Mohamed (1996) are marked with open squares and data from Fornasier et al. (2006) with star symbols. Lines represent albedo-slope dependences used by different authors for albedo calculations. High-albedo asteroids are marked by their spectral types (V and A). E-type asteroids are designated by number. |
