Radial evolution of the temperature and temperature anisotropy of protons and α particles. T_p and T_p⊥/T_p∥ are shown in the top row and the second row. The left column is for solar minimum. The right column is for the solar maximum of solar activity. T_α and T_α⊥/T_α∥ are shown in the third row and the bottom row. The bold dashed horizontal line represents T_⊥/T_∥ = 1.
