Abstract
In this paper, we present astrometric results derived from reduction of 65 lightcurves made in 1995-1996 during the PHESAT95 campaign of observation of Saturnian satellites mutual events. These results have an accuracy of about 20-30 mas and are compared to those obtained by Emelianov et al. (1997) for the 3 events observed in Crimea and Kazakhstan. We also discuss the reliability of the method used for reducing the lightcurves from the mutual events of 1980.

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 http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
