This package is designed to identify and analyze discontinuities in time series data.
- Finding the discontinuities, see this
notebook
- Corresponding to limited feature extraction / anomaly detection
- Calculating the properties of the discontinuities, see this
notebook
- One can use higher time resolution data
For how to use this project as a python library, please see this page.

Notations:
-
$\vec{B}$ : Magnetic field -
$B$ : Magnetic field magnitude
-
b_mag: mean of magnetic field magnitude across the discontinuity -
db_over_b:$|\Delta B|/\bar{B}$ , Change in magnetic field magnitude over magnetic field magnitude (mean)- see Fig.14 in Tsurutani and Smith (1979)
-
rotation_angle: Rotation angle across the discontinuity- see Fig.12 in Tsurutani and Smith (1979)
- see Fig.11 in Söding et al. (2001)
-
bn_over_b:$\bar{B}_N/\bar{B}$ : Normal component of magnetic field over magnetic field magnitude (mean)
