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 # References: # M.L.
