Phase curves of small bodies from the SLOAN Moving Objects Catalog

Context. Extensive photometric surveys continue to produce enormous stores of data on small bodies. These are typically sparsely obtained at arbitrary (or unknown) rotational phases. Therefore, new methods for processing such need be developed make the most these vast catalogs. Aims. We aim a method recreating phase curves bodies by considering uncertainties introduced nominal errors in magnitudes and effect variations. use SLOAN Moving Objects Catalog as benchmark construct all u ?, g r i z ? filters. From curves, we obtain absolute them set up colors, which colors asteroids that not affected changes angle. Methods. selected objects with ?3 observations taken least one filter spanning over minimum 5 degrees combines Monte Carlo simulations Bayesian inference estimate using HG 12 * system. Results. almost 15 000 about including five The compatible previously published support our method. Conclusions. is fully automatic well suited run based large amounts data. Moreover, it includes whole distribution possible states producing what possibly less precise values, is, larger uncertainties, but more accurate, namely, closer actual value. To knowledge, this work first include variations manner.
