Due to an error at the publisher, in the published article multiple values were incorrect in Table 1 and in the text. Accordingly, Table 1 has been reproduced below, and the values in the text should be cited as follows.

Table 1. Sampling Intervals, 0.5–2 MeV Nucleon⁻¹ ³He/⁴He and Fe/O Ratios at ∼0.193 and ∼18 MeV Nucleon⁻¹, γ_a, γ_b, and Break Energies E_B from the Band Function Fits, and the Low-energy Spectral Index γ_Lo, and Intersection Energy E_I from Double Power-law Fits to the ∼0.1–100 MeV Nucleon⁻¹ O Spectra

Notes.

^aFit parameters with relative uncertainties >100% indicate poor fits to the data and have been eliminated from this table and the analyses. ^bAccompanied by Ground Level Enhancements (see Mewaldt et al. 2012).

In the final paragraph of Section 3.2, the final sentence should read, "correlation coefficient r ∼ 0.103 for N = 36 has a >55% probability of being exceeded by two uncorrelated quantities."

In the first paragraph of Section 3.5, the third sentence should read, "We used the technique described in Desai et al. (2003, 2006) to subtract the background and contributions to spill-over from the more abundant ⁴He peak to the ³He mass range between 2.8 and 3.2 AMU."

In the first paragraph of Section 3.7, the second sentence should read, "We identify a new set of variables by eliminating those that do not contribute significantly to the overall variability in the data set through a multivariate, principal component analysis (PCA) that uses the Karhunen—Loeve Transform method (see Murtagh & Heck 1987) for 25 SEP events using the following 8 variables: O low-energy and high-energy SEP Band-parameters, Θ, γ_a, and γ_b; O break energy E_B; CME speed V_CME; flare longitude; peak proton flux P_P; the Fe/O ratios at ∼15–21 and ∼0.16–0.23 MeV nucleon⁻¹ Fe/O₁₈ and Fe/O_0.2."

IOP Publishing sincerely regrets these errors.
