Geometric Distortion Calibration with Photo-lithographic Pinhole Masks for High-Precision Astrometry
Maxwell Service, Jessica R. Lu, Mark Chun +5
Adaptive optics (AO) systems deliver high-resolution images that may be ideal for precisely measuring positions of stars (i.e. astrometry) if the system has stable and well-calibra…

The InfraRed Imaging Spectrograph (IRIS) for TMT: photometric precision and ghost analysis
Nils Rundquist, Gregory Walth, Shelley A. Wright +11
The InfraRed Imaging Spectrograph (IRIS) is a first-light instrument for the Thirty Meter Telescope (TMT) that will be used to sample the corrected adaptive optics field by NFIRAOS…
