Abstract
The application of the Maximum Entropy method for sky imaging with the SPI instrument on INTEGRAL is described. While intended primarily for extended emission, point sources are also mapped by this method. The technique is implemented as the program spiskymax in the data analysis distribution provided by the INTEGRAL Science Data Centre. We briefly introduce the method, describe the particular requirements for the application to SPI, and show some example images using flight data from the early mission.


Key words: data analysis -- gamma rays -- coded masks -- INTEGRAL

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.
