  We examine whether the gravitational shear--intrinsic ellipticity (GI)
correlation function of the luminous red galaxies (LRGs) can be modeled with
the distribution function of a misalignment angle advocated recently by Okumura
et al. For this purpose, we have accurately measured the GI correlation for the
LRGs in the Data Release 6 (DR6) of the Sloan Digital Sky Survey (SDSS), which
confirms the results of Hirata et al. who used the DR4 data. By comparing the
GI correlation functions in the simulation and in the observation, we find that
the GI correlation can be modeled in the current $\Lambda$CDM model if the
misalignment follows a Gaussian distribution with a zero mean and a typical
misalignment angle $\sigma_\theta=34.9^{+1.9}_{-2.1}$ degrees. We also find a
correlation between the axis ratios and intrinsic alignments of LRGs. This
effect should be taken into account in theoretical modeling of the GI and
intrinsic ellipticity--ellipticity correlations for weak lensing surveys.
