Abstract

The article treats on astrometric measurements obtained using NEEMO system of telescopes and the improvement by applying a distortion model. Astrometric measurements for T05 show a stable value of residuals, independent of distortion model, while the measurements for T03 are improved by a factor three when use a quartic distortion model.
