ELT/MICADO astrometric calibration: I. Stability under sky de-rotation
MICADO will be a first-light instrument at the Extremely Large Telescope (ELT), with the capability of diffraction-limited relative astrometry down to the 50 μas level. High-precision relative astrometry with MICADO on the ELT requires accurate characterization and calibration of geometric distortion across the full in...
