Anisotropy and intensity time profiles of protons as observed by, from left to right, STEREO-B/LET, Wind/3DP, and STEREO-A/LET. The panels show almost the same information as in Fig. 3, but with 16 sectors in STEREO/LET, eight front-side (reddish colours) and eight back-side sectors (bluish colours). The energies examined are 1.8–3.6 MeV for both STEREO and 2.1 MeV for Wind. The vertical lines indicate the CME-driven shock arrival to the spacecraft.
