Abstract
A probability theoretical method is presented which enables the calculation of microlensing autocorrelation functions. Following an idea of Deguchi and Watson the Holtsmark-Markov method is employed to reduce this calculation to the numerical evaluation of twodimensional integrals. Comparing these results with autocorrelation functions calculated from measurements, consistent preliminary information about the individual lens system B1600+434 has already been obtained.


Key words: methods: numerical -- gravitational lensing -- microlensing -- quasars: individual: B1600+434

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.
