Ghelfi et al. (2016) performed a global analysis of top-of-atmosphere data (with the recent PAMELA, BESS, and AMS-02 data) to obtain H and He interstellar (IS) fluxes and their uncertainties. A simple parametric formula was provided for the IS fluxes (shown in their Fig. 5) because they are of interest for a wide range of astrophysics problems. However, the parametric form of Eq. (8) contains an error and all coefficients c12 and in Table 3 are incorrect.
As discussed in Ghelfi et al. (2016), the first five columns of Table 1 are coefficients for the median and 1- and 2σ credible intervals from the Markov chain Monte Carlo (MCMC) analysis (without Voyager data), to be considered as a high estimate of the H and He IS fluxes (not valid below 400 MeV/n). The last column provides the best-fit including Voyager data (assumed insterstellar), to be considered as a low estimate of the IS H and He fluxes.
