Erratum: “Inference of the Local Interstellar Spectra of Cosmic-Ray Nuclei Z ⩽ 28 with the GALPROP–HELMOD Framework” (2020, ApJS, 250, 27)

We noticed two typos in Appendix C.2.1 in the published article, in the analytical parameterization of the local interstellar spectrum of He nuclei, Equation (C2), and in an expression for T(x), Equation (C32). The correct expressions are provided below:

$$F_{\text{He}}(R)=\{\begin{array}{ll}a-bR+c\sqrt{\sin (R)}+\left[dRG{(fR)}^2-gR\right]\sin (R)-(h+iR)G(fR),\hfill & R⩽2.5\text{GV,}\hfill \\ R^{-2.0}\left[l+\frac{m}{R}-\frac{n}{R^2}+\frac{o}{p+qR}+r\tanh \left(\frac{s}{t+uR}\right)-v{z}^{\frac{3}{R}}\right],\hfill & R>2.5\text{GV}.\hfill \end{array}$$ (C2)

Here F_He (R) is the differential intensity in units (m² s sr GV)⁻¹, R is the particle rigidity in GV, G(x) is a function defined in Equation (C30), and the values of the fitting parameters a to z are given in Table C1. The function T(x) is defined as:

$$T(x)={\left(3.764x^2\right)}^{xG{(x)}^{3.764x}}.$$ (C32)
