HD 32297 6R/PSFTSC imaging (north up, east left) from all WedgeA-0.6 and -A1.0 observations rotated 415 eastward from north to place the inner disk plane on the image horizontal. The three display stretches illustrate the complexity and morphology of light-scattering debris structures over a dynamic range of 13 mag arcsec−2. Top: log10 display from [−3] to [+2.13] dex counts s−1 pixel−1 (approximately 0.002 to 24 mJy arcsec−2). Middle: square root display from 0 to 1 counts s−1 pixel−1 (0–175 μJy arcsec−2). Bottom: linear from −0.01 to +0.2 counts s−1 pixel−1 (approximately −1.8 to 35 μJy arcsec−2). Field: 460 × 186 STIS pixels (232 × 94). The red circle r = 03 (6 STIS pixels = width of WedgeA-0.6).
