Visual binary stars with partially missing data: Introducing multiple imputation in astrometric analysis
Ruben M. Claveria, Rene A. Mendez, Jorge F. Silva +1
Partial measurements of relative position are a relatively common event during the observation of visual binary stars. However, these observations are typically discarded when esti…
Optimality of the Maximum Likelihood estimator in Astrometry
Sebastian Espinosa, Jorge F. Silva, Rene A. Mendez +2
The problem of astrometry is revisited from the perspective of analyzing the attainability of well-known performance limits (the Cramer-Rao bound) for the estimation of the relativ…
Analysis of the Bayesian Cramer-Rao lower bound in astrometry: Studying the impact of prior information in the location of an object
Alex Echeverria, Jorge F. Silva, Rene A. Mendez +1
Context. The best precision that can be achieved to estimate the location of a stellar-like object is a topic of permanent interest in the astrometric community. Aims. We analyse b…
