TL;DR: In this article, the authors used sparse photometry from selected observatories from the AstDyS database (Asteroids- Dynamic Site), either alone or in combination with dense lightcurves, to determine new asteroid models by the lightcurve inversion method.

TL;DR: In this paper, the authors used the lightcurve inversion method to predict the orientation of an asteroid for the time of an occultation by scaling the shape model to fit the occultation chords, which can determine the asteroid size with a relative accuracy of typically ∼10%.

TL;DR: In this article, the authors compared the observed pole latitude distribution of all asteroids with known convex shape models with the simulated pole latitude distributions and presented 119 new asteroid shape models derived from combined dense and sparse-in-time photometry.

TL;DR: In this article, the authors used a large-scale dataset of optical data from more than 100 observers who submittheir optical data to publicly available databases and derived 3D shape models of asteroids together with their rotation periods and orientations of rotation axes.

TL;DR: In this article, the authors used the lightcurve inversion method to obtain rotation parameters and coarse shape models of selected asteroids, which can be derived from disc-integrated photometry.
