Abstract:
We present physical models of ten asteroids obtained by means of
lightcurve inversion. A substantial part of the photometric data was
observed by amateur astronomers. We emphasize the importance of a
coordinated network of observers that will be of extreme importance
for future all-sky asteroids photometric surveys.
Description:
The files contain asteroid brightness and geometry for corresponding
epochs. These files were used for deriving shape models and spin
states of the asteroids. Individual lightcurves within a file are
separated by an empty line, all lightcurves are relative.
