    • Analysis of the Cramér-Rao Bound in the Joint Estimation of Astrometry and Photometry 
      Méndez Bussard, René Alejandro; Silva Sánchez, Jorge; Oróstica, Rodrigo; Lobos, Rodrigo (The Astronomical Society of the Pacific, 2014)
      In this paper, we use the Cramér-Rao lower uncertainty bound to estimate the maximum precision that could be achieved on the joint simultaneous (or two-dimensional) estimation of photometry and astrometry of a point source ...
    • Optimality of the maximum likelihood estimator in astrometry 
      Espinosa, Sebastian; Silva, Jorge; Mendez, Rene; Lobos, Rodrigo; Orchard Concha, Marcos (EDP Sciences, 2018)
      Context. Astrometry relies on the precise measurement of positions and motions of celestial objects. Driven by the ever-increasing accuracy of astrometric measurements, it is important to critically assess the maximum ...
