  1. Properties of the precipitating electrons, i.e. energy flux (EF), characteristic energy (EC), and type of energy distributions are indicated. We also provide the frequency and the intensity of the moon-induced radio emissions, as well as the UV brightness of the auroral footprints. References corresponding to the derived parameters are indicated in the column headings.
