Observational constraints on the Φ(⁸B) and Φ(7Be) values. The green open circle with error bars shows the constraints derived using all experimental neutrino data available up to 2016 (Bergström et al. 2016; Orebi Gann et al. 2021), which is used in this study. The orange ellipses show the constraints in Agostini et al. (2018) from the Borexino experiments only (right) and from using available experimental data (left). The gray, blue, and pink shaded regions indicate the constraints from the KamLAND experiments (Gando et al. 2015), from Aharmim et al. (2013) with the Sudbury Neutrino Observatory (SNO), and from Anderson et al. (2019) with the SNO+, respectively.
