Database of Freja charging events

This is the database of PDF plots of Freja charging events. Please read the guide to the plots for more information. This page works properly only with Netscape 4 or Internet Explorer 4 or higher.

On the following table, you just need to click on the button to sort the data in ascendant or descendant order and to display the results below. Please wait during the sort: it can take a few minutes before the display.
