The large value of S _ { 17 } ( 0 ) = 22.1 \pm 0.6 eV-b , reported by the Seattle group , suggests a larger total ^ { 8 } B solar neutrino flux . Together with the two high precision values quoted for S _ { 34 } ( 0 ) it is either 20 % or 9 % larger than measured by SNO . While the accuracy of the Standard Solar Model has recently been revisited , precise nuclear inputs are still relevant , but a detailed examination of current data on S _ { 17 } ( as opposed to an examination of S _ { 17 } ( 0 ) only ) excludes quoting S _ { 17 } ( 0 ) with sufficiently small uncertainty . In contrast to suggestions that S _ { 17 } ( 0 ) is now known with the ( impressive ) accuracy of \pm 3 % , the exact value of S _ { 17 } ( 0 ) is dependent on the choice of the data and the choice of theory used for extrapolation . In addition recent high precision results ( including the Seattle data ) on S _ { 17 } which are in good agreement , still differ on the measured slopes , as does the theory , precluding an accurate extrapolation to zero energy of the consistent data . Using a common extrapolation of only the consistent high precision data , suggests a value of S _ { 17 } ( 0 ) = 21.2 \pm 0.5 eV-b , but a value equal to or smaller than 19.0 eV-b can not be excluded due to the uncertainty in the extrapolation , leading to an additional error of ^ { +0.0 } _ { -3.0 } eV-b . A proposal to remedy this situation is discussed .
