A dataset of MHD discontinuity structures detected by the Magnetospheric Multiscale Mission

Readme file for the MHD discontinuity dataset established in the paper entitled "New Insights into Nature of Solar Wind Discontinuities Through MADD Technique" by Y. T. Song & Y. Y. Liu et al, to be published in the Astrophysical Journal. This dataset is created by using the Magnetospheric Multiscale observations from 9-Oct-2017 to 10-May-2025. The two CSV files (i.e., list_candidate.csv & list_final.csv) provide two event lists organized in the following manner:1) list_candidate, which is a 1,541,473*2 data array. The first and second columns correspond to the detection time (ISDAT epoch, the number of seconds since 1-Jan-1970) and duration of those discontinuity candidates;2) list_final, which is a 101,383*3 data array. Three columns correspond to the detection time, duration and position (0: solar wind; 1: magnetosheath; 2: Magnetosphere; -1: uncertain) of discontinuity structures that have been further checked and selected. We welcome any further analysis of this database. For questions, please contact the corresponding author, Yangyang Liu ([e-mail]).
