Abstract: (AIP)
The Auger Engineering Radio Array (AERA) is located within the Pierre Auger Observatory and currently consists of 24 self-triggered radio stations. Observation of radio signals from cosmic rays is confirmed by the surface detector (SD) stations of the Observatory which provide well-calibrated information on the cosmic-ray energies and arrival directions. The response of the radio stations has been thoroughly calibrated to enable the reconstruction of the incoming electric field. For estimating the cosmic-ray energy we use the maximum absolute value of the measured electric field vector corrected for the incoming direction and the distance to the shower core. Performing a preliminary energy calibration using the SD information, we observe that the defined radio energy estimator provides an approximately linear dependency on the cosmic-ray energy.- 96.50.sd
