This data set contains definitive goniopolarimetry parameters derived from STEREO-A WAVES HFR (High Frequency Receiver) high resolution data (125 - 16025 kHz).

Level 3a data are computed asssuming: (i) incoming wave properties do not change over three successive antennas-pair measurements, (ii) signals measured by an antenna are the same on the two receiver channels, (iii) radio sources have an uniform brightness distribution.

Data provided are publicly available. If used in presentations or publications, please acknowledge STEREO/Waves Investigation (M. Maksimovic and S. D. Bale, PIs). We recommend the data users to contact the STEREO/Waves team early in their study. For reporting purposes, we request bibliography information for any publication, etc., using these data. Please send information on the use of this data to: M. Maksimovic (PI). We suggest to add the following lines into the acknowledgments: The authors acknowledge CNES (Centre National d'Etudes Spatiales), CNRS (Centre National de la Recherche Scientifique), and Observatoire de Paris for support to the STEREO/Waves team and the CDPP (Centre de Données de la Physique des Plasmas) for the provision of the STEREO/Waves data.
