We present revised Be-7(p,gamma)B-8 S factors based on our previously published measurements, using a more detailed target analysis and improved stopping powers. Extrapolating our data below the 1(+) resonance to solar energies using the latest cluster model calculations of Descouvemont, we find that S-17(0) = 21.5 +/- 0.6(expt) +/- 0.7(theor) eV b. Fitting all modern, low-energy (p,gamma) data with the same theory, we find a best value of S-17(0) = 20.9 +/- 0.6(expt) +/- 0.7(theor) eV b.
