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 $(A-\lambda)$ plot catalogue of asteroids" (Riccioli & Blanco 1995) as a starting point, the amplitude-magnitude (AM) method (Zappalà et al. 1983a) was adopted.
Due to the poor data available, it was possible to apply the (AM) method only to 30 asteroids. For more than half of these objects no previous determination of pole coordinates and shape exists in the literature.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access.

An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account.
    In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see You should disable this module if you wish to use the OpenURL server that you or your library have defined.
