The Error Bar Stayed Small While the Astrometry Drifted
ADORA simulations showed high-order wavefront mismatch could bias a solution without widening its local uncertainty.
Summary
ADORA simulations showed high-order wavefront mismatch could bias a solution without widening its local uncertainty.
The differentiable optical model jointly estimates astrometric and instrument state for the proposed SHERA mission. Matched simulations reached roughly 11 microarcseconds scatter, but unmodeled wavefront error produced strong bias with deceptively small posterior sigma.
Why it matters
ADORA simulations showed high-order wavefront mismatch could bias a solution without widening its local uncertainty.
Limits and context
No additional limitation was separately recorded.
Key claims
