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.
