To obtain a statistically reliable sample of minor planets
with known rotation axis orientation and axes ratios, a selection of photometric
lightcurves sufficiently covered to give the elements needed for applying the
computation methods of the rotational elements was made.
Using the data reported in the "Amplitude-longitude plot
catalogue of asteroids"
(Riccioli & Blanco
1995) as a starting point,
the amplitude-magnitude
method
(Zappalà et al. 1983a) was
adopted.
Due to the poor data available, it was possible to apply the
method only
to 30 asteroids. For more than half of these
objects no previous determination of pole coordinates and
shape exists in the literature.
