This data set contains the  electron pitch angle distributions (from 0° to 180°) as a function of energy at the BURST cadence (2 s).
The pitch-angles are calculated in the plasma frame based on ion velocity from the PLASTIC instrument (if data is available, according to a flag given in the dataset).
The data is provided in units of phase space density. The reference frame is related to the instrument frame.

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:

quality_index_0 = 0 --> B field INSIDE instrument field-of-view: ALL PA covered.
quality_index_0 = 1 --> B field OUTSIDE instrument field-of-view: NOT ALL PA covered.

quality_index_1 = 0 --> PA distributions corrected for ion bulk flow (from STEREO/PLASTIC) 
quality_index_1 = 1 --> PA distributions NOT corrected for ion bulk flow (Data unavailable)
