1  BASILICO 2023 obtained this result by combining the newly developed Correlated Integrated Directionality (CID)-based CNO result obtained by using the complete Borexino data-taking period from 2007 to 2021, with a spectral fit of the Phase-III dataset (from July 2016 to October 2021, characterized by a thermally stable detector). Note that the directional information is independent from the spectral information on which the previous CNO solar neutrino measurements by Borexino were based. Neutrino flavor conversion was taken into account.
2  APPEL 2022 obtained this result from the measured ${{\mathit \nu}_{{{e}}}}{{\mathit e}}$ elastic scattering rate over the period between January 2017 and October 2021, assuming the MSW-LMA oscillation parameters derived by ESTEBAN 2020A. The exposure corresponding to this data is 1431.6 days ${\times }$ 71.3 tons.
3  AGOSTINI 2020D obtained this result from the measured ${{\mathit \nu}_{{{e}}}}{{\mathit e}}$ elastic scattering rate over the period between July 2016 to February 2020, assuming the MSW-LMA oscillation parameters derived by CAPOZZI 2018.
4  AGOSTINI 2018B obtained this result from an upper limit of the ${{\mathit \nu}_{{{e}}}}{{\mathit e}}$ elastic scattering rate for the CNO neutrinos over the period between December 2011 and May 2016, assuming the MSW-LMA oscillation parameters derived by ESTEBAN 2017.
