Query: Measurement of Time-Dependent CP Asymmetry in B0 --> KS pi0 gamma Decays   We measure the time-dependent CP asymmetry in B0 --> K_S0 pi0 gamma decays
for two regions of K_S0-pi0 invariant mass, m(K_S0 pi0), using the final BABAR
data set of 467 x 10^6 BBbar pairs collected at the PEP-II e+e- collider at
SLAC. We find 339 +/- 24 B0 --> K*0 gamma candidates and measure S_{K* gamma} =
-0.03 +/- 0.29 +/- 0.03 and C_{K* gamma} = -0.14 +/- 0.16 +/- 0.03. In the
range 1.1 < m(K_S0 pi0) < 1.8 GeV/c^2 we find 133 +/- 20 B0 --> K_S0 pi0 gamma
candidates and measure S_{K_S0 pi0 gamma} = -0.78 +/- 0.59 +/- 0.09 and C_{K_S0
pi0 gamma} = -0.36 +/- 0.33 +/- 0.04. The uncertainties are statistical and
systematic, respectively.
