(A) PSF-subtracted WedgeA-0.6 images of the HD 32297 CS disk using unintentionally color-mismatched PSF star; left to right: V05, V06, V08, V01, V02, V04. (B) Masking out the disk signal from the corresponding images. (C1) Masked-median combination of all six images in row (B). (C2) Radial profile image from image C1 excluding unsampled regions. (C3) Using panel (C2) as a proxy to estimate the oversubtraction in unsampled regions. (C4) The final chromatic correction template to apply to the images in row (A). (D) PSF-subtracted images of the HD 32297 disk after chromatic correction (row A images minus C4). (E) Comparison to PSF-subtractions using a non-contemporaneous calibration PSF star, a Pic, with a closely color-matched Δ(B − V) = −0.02.
