Effect of baryons on the shear power spectrum C_l, expressed as a relative percentage difference from the pure dark matter model. Here the source galaxies are assumed to be at redshifts ﹩z_{s}﹩ of 0.6, 1.0, and 1.5, respectively. The dashed lines are the predictions from our nonradiative run, while the solid lines give the results for the star formation run.
