   \caption{Parameters for some "Hot Jupiters''. 
   The values used for the calculation of the magnetic moments are given in units normalized to 
   Jupiter. The lower part shows the scaling results for a stellar system of 4.6~Gyr age: 
   planetary dipole moment, total emitted 
   radio power, radio flux at 1~AU from the planet,  radio flux at Earth (distance $s$)
   and maximum
   frequency. Values calculated for Jupiter are given for comparison. Sources of parameters:
