Pixel-Level Calibration for Space-Based High Precision Astrometry Using Young's Fringes
Hugo Rousset, Eric Thiébaut, Chloé Rey +8
The detection of Earth-like exoplanets via astrometry necessitates centroiding precision at the 0.3 microarcsec level, thereby imposing stringent constraints on the focal plane geo…
