Dataset for the paper "The magnetopause deformation indicated by fast cold ion motion"

This dataset is used for the paper "The magnetopause deformation indicated by fast cold ion motion" and contains pubilicly available data of MMS dayside magnetopause crossing events with fast cold ion motion from 2015 to 2021, which includes crossing time and position, solar wind parameters (dynamic pressure, IMF, solar wind speed), the normals from the model (Shue97) and observations (Timing and MVA methods), the normal speed of magnetopause (VMP) from Timing method, the component speeds of cold ion along normal and tangential directions, the deflection angle between the observed magnetopause normal and the prediction, and the magnetopause deformation amplitude of each event in geocentric solar magnetospheric (GSM) coordinates.本数据集用于论文《由快速冷离子运动揭示的磁层顶形变》，包含2015年至2021年间公开可用的磁层多尺度（Magnetospheric Multiscale, MMS）日侧磁层顶穿越事件数据，具体涵盖穿越时刻与位置、太阳风参数（动压、行星际磁场（Interplanetary Magnetic Field, IMF）、太阳风速）、模型（Shue97模型）与观测（计时法与最小方差分析法（Minimum Variance Analysis, MVA））得到的磁层顶法向量、计时法得到的磁层顶法向速度（VMP）、冷离子沿法向与切向的分速度、观测磁层顶法向量与预测值之间的偏转角，以及各事件在地心太阳磁层（GSM）坐标系下的磁层顶形变振幅。
