spaceKLIP PSF subtraction yields high S/N detection of β Pic b in the F210M and F410M bands (upper left and upper right, respectively). The newly discovered planet β Pic d (A. Gibbs et al. 2026; B. J. Sutlieff et al. 2026) is visible in the F410M-band image. KLIP forward models using stpsf models successfully describe the detected planet signal and provide precise time-averaged photometry estimates (lower panels).
