Abstract
Accurate measurement of exoplanetary masses is a critical step in addressing key aspects of NASA’s science vision. Astrometry can detect and measure masses of planets orbiting the target star. However, the signal for earth-analogs is in the sub-microarcsecond regime, well beyond our instrumentation. In this paper, we study part of an astrometry error budget for the HabEx Workhorse Camera and we propose a calibration approach to reach earth-analog sensitivity.
