Demodulated p and He data () as a function of E_k/n. The low-energy data and the associated modulation parameter are: AMS-01 (Alcaraz et al. 2000 for H; and AMS Collaboration et al. 2000 for He) with φ = 600 MV; CAPRICE94 (Boezio et al. 1999) and CAPRICE98 (Boezio et al. 2003) with φ = 650 MV and 600 MV respectively; IMAX (Menn et al. 2000) with φ = 750 MV; and the series of BESS balloon flights BESS93 (Wang et al. 2002) BESS97 (Shikaze et al. 2007), BESS98 (Sanuki et al. 2000; Shikaze et al. 2007), BESS99 (Shikaze et al. 2007), BESS00 (Shikaze et al. 2007), and BESS02 (BESS-TeV, Haino et al. 2004; Shikaze et al. 2007), for which φ = 700 MV, 491 MV, 591 MV, 658 MV, 1300 MV, 1109 MV respectively. The intermediate and high-energy data are: ATIC-2 (Panov et al. 2009), CREAM-I (Ahn et al. 2010a), JACEE (Asakimori et al. 1998), MUBEE (Zatsepin et al. 1993), RICH-II (Diehl et al. 2003), RUNJOB (Derbina et al. 2005), SOKOL (Ivanenko et al. 1993), and Ichimura et al.
