The antenna beam patterns plotted here were made using
software written by Dr. Andrew Senior with contributions by
Dr. Michael T. Rietveld. Before using these plots in 
publications please consult us, so that we can confirm 
their validity. An acknowledgement to A. Senior should be made.

The log files used as input to this software are available through EISCAT.

A perfectly conducting ground has been assumed in the model,
which is not completely realistic. We think that the 
actual ERP may only be about 75% of the calculated value.
