We report a fully inclusive measurement of the flavor changing neutral current decay $b\\ensuremath{\\rightarrow}s\\ensuremath{\\gamma}$ in the energy range $1.8\\text{ }\\mathrm{G}\\mathrm{e}\\mathrm{V}\\ensuremath{\\le}{E}_{\\ensuremath{\\gamma}}^{*}\\ensuremath{\\le}2.8\\text{ }\\mathrm{G}\\mathrm{e}\\mathrm{V}$, covering 95% of the total spectrum. Using $140\\text{ }\\mathrm{f}{\\mathrm{b}}^{\\mathrm{\\ensuremath{-}}\\mathrm{1}}$, we obtain $\\mathcal{B}(b\\ensuremath{\\rightarrow}s\\ensuremath{\\gamma})=(3.55\\ifmmode\\pm\\else\\textpm\\fi{}{0.32}_{\\ensuremath{-}0.31\\ensuremath{-}0.07}^{+0.30+0.11})\\ifmmode\\times\\else\\texttimes\\fi{}{10}^{\\ensuremath{-}4}$, where the errors are statistical, systematic, and from theory corrections. We also measure the first and second moments of the photon energy spectrum above $1.8\\text{ }\\mathrm{G}\\mathrm{e}\\mathrm{V}$ and obtain $\\ensuremath{\\langle}{E}_{\\ensuremath{\\gamma}}\\ensuremath{\\rangle}=2.292\\ifmmode\\pm\\else\\textpm\\fi{}0.026\\ifmmode\\pm\\else\\textpm\\fi{}0.034\\text{ }\\mathrm{G}\\mathrm{e}\\mathrm{V}$ and $\\ensuremath{\\langle}{E}_{\\ensuremath{\\gamma}}^{2}\\ensuremath{\\rangle}\\ensuremath{-}\\ensuremath{\\langle}{E}_{\\ensuremath{\\gamma}}{\\ensuremath{\\rangle}}^{2}=0.0305\\ifmmode\\pm\\else\\textpm\\fi{}0.0074\\ifmmode\\pm\\else\\textpm\\fi{}0.0063\\text{ }{\\mathrm{G}\\mathrm{e}\\mathrm{V}}^{2}$, where the errors are statistical and systematic.
