ADC_Keywords: Minor planets; Photometry Keywords: techniques: photometric - minor planets: asteroids Abstract: 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. Description: The files contain asteroid brightness and geometry for corresponding epochs. These files were used for obtaining shape models and spin states of the asteroids. Individual lightcurves within a file are separated by an empty line, all lightcurves are relative. File Summary:
