Orbit determination with very short arcs. I admissible regions

Most asteroid discoveries consist of a few astrometric observations over a short time span, and in many cases the amount of information is too limited to compute a full orbit according to the least squares principle. We investigate whether such a Very Short Arc may nonetheless contain significant or...
