# Description: Stereo Plastic STB Alfvén Wave List
# A description and the original list can be found at:
# https://stereo-ssc.nascom.nasa.gov/data/ins_data/plastic/level3/Alfven_Waves/

# Data provided by the PLASTIC team at the University of New Hampshire is under NASA grant NNX15AU01G.
# Alfvén wave data provided here is courtesy of W. Yu and C. Farrugia.

# The table lists some Alfvén waves observed by the STEREO spacecraft from year 2007 to year 2014.
# They are identified while searching for small solar wind transients (STs).

# STs were observed frequently in the solar wind (Yu et al., 2014, 2016).
# However, as pointed out by Marubashi et al. [2010] and Cartwright and Moldwin [2010],
# some solar wind Alfvénic structures can be mistaken for STs. For this reason, we need to identify Alfvénic structures.
# See the README at https://stereo-ssc.nascom.nasa.gov/data/ins_data/plastic/level3/Alfven_Waves/
# for a description of the correlations we use to identify structures.
# We require all three correlations (RX, RY, RZ) to be greater than 0.5, or two greater than 0.6 and the other greater than 0.3,
# which is similar to the criterion in Cartwright and Moldwin [2008].

# These data are delivered to the public domain on a regular basis.
# Efforts are made to include the latest known calibration and background determinations,
# however, these are expected to undergo revision. We therefore suggest that users regularly return to this page,
# and make sure to get the most recent revision.
# If used in presentations or publications:
# We strongly suggest that Dr. Wenyuan Yu (unhyuan@gmail.com) and Dr. Charlie Farrugia (charlie.farrugia@unh.edu) be contacted
# to ensure that you are working with the latest release.
# Please acknowledge STEREO PLASTIC Investigation (A.B. Galvin, PI) and NASA grant NNX15AU01G.
# For reporting purposes, we request bibliography information for any publication, etc., using these data.
# Please send information on the use of this data to the PLASTIC PI:
# Dr. A.B. Galvin toni.galvin@unh.edu  
# If you have questions regarding the data formats, please contact the PLASTIC Data System Manager:
# Dr. Lorna Ellis lorna.ellis@unh.edu
