Description
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.
