Abstract (from CDS):

We analyze photometric observations of the three main-belt asteroids 350 Ornamenta, 771 Libera, and 984 Gretia, conducted over a twelve-year interval. Our data and those of other authors allow us to determine pole and shape models using the lightcurve inversion technique. In all three cases, a single pole solution was obtained without any significant mirror solution: Ornamenta - P=9.180414h, λp=184°, βp=-29° Libera - P=5.890423 h, λp=64°, βp=-78° Gretia - P=5.778025h, λp=245°, βp=+52°. This analysis and the development of asteroid models increase the set of asteroids with known spin and shape parameters, which consists of only around 100 objects.
