HD 32297 six-roll combined PSFTSC imaging (north up, east left) from all WedgeA-0.6 and WedgeA-1.0 observations. The grayscale image (left) and isophotal contours (right) both log10 display from [−3.5] to [+2.15] dex counts s−1 pixel−1 (≈0–25 mJy arcsec−2). Field: 380 × 340 STIS pixels (193 × 172), north up, east left. The red circle indicates a disk major axis IWA of r = 03 (6 STIS pixels = width of WedgeA-0.6). 1σ pixel-to-pixel noise assessed in regions far from disk is approximately 0.0032 counts s−1 pixel−1 (0.56 μJy arcsec−2).
