Goal: Provide point spread function (PSF) estimates for each point in the science field for all NGS and LGS AO science observations taken with NIRC2 and OSIRIS on Keck. AIROPA Project: We are developing PSF-reconstruction techniques that better capture the spatial variability of the AO PSF. Keck AO Performance Characterization and Prediction Goal: Using big data sets from Keck AO, understand what factors effect the AO performance and what hardware or operational procedures can be improved. These same data can be used to predict AO performance using machine learning algorithms. Keck AO Precision Calibration Unit (PCU) Goal: Build a new precision calibration unit for the Keck I and Keck II telescopes that includes a pinhole mask used for frequent calibrations of the geometric distortion solution. This will improve our astrometric accuracy by >5x. |

'imaka ‘imaka is a wide-field (~20 arcmin) ground-layer adaptive optics (GLAO) system that yields ~2x improved seeing on the University of Hawaii 2.2 m telescope. Keck GLAO Goal: Develop a conceptual design for a future Keck GLAO system to feed FOBOS, MOSFIRE, or LRIS. TNO Adaptive Secondary Mirror Goal: TNO will develop a new adaptive secondary mirror (ASM) that is more robust and requires less power than current ASMs. We will deploy and tests the new ASM on-sky on the UH 2.2 m telescope. |

Roman Astrometry We have developed compelling science cases for the high astrometry precision that Roman will deliver. These science cases help set requirements and operational or calibration procedures for Roman. Our work on the potential science impact of Roman for understanding stellar mass black holes is described on the Black Holes page. |
