Disk-to-star flux ratio as determined from the Q_φ image, which only includes polarized scattered light from the disk, and an unsaturated total intensity image, which is dominated by the stellar halo. The three data points are the flux ratios in R, I, and J-band with 3σ error bars. The dashed line shows a weighted least squares fit of a linear function and the solid lines are the normalized transmission curves of the three filters.
