Description
PSPT, centerpiece of NSF's RISE program on solar radiative-output variability: a 15 cm refractor producing full-disk 2048x2048 images in blue and red continuum and Ca II K bands at 0.1% pixel-to-pixel photometric precision; NSO-built units operate at MLSO and Rome, with SRPM image masks for solar feature classification.
