Labelled dataset of Cassini magnetometer data
Description
Filename:
Cassini_2006_labelled_data.txt
Contains 1-minute resolution Cassini data during year 2006 with times of reconnection events (plasmoids, dipolariztions, Travelling compression regions) labelled. 99 events as per:
Jackman, C.M., C. M., G. Provan, and S. W. H. Cowley (2016), Reconnection events in Saturn's magnetotail: Dependence of plasmoid occurrence on planetary period oscillation phase, J. Geophys. Res. Space Physics, 121, doi:10.1002/2015JA021985.
Data:
Year (all 2006 for this example)
DOYFRAC: Day of year fraction as a timestamp, range from 1-365
BR_KRTP: Radial component of the magnetic field in KRTP co-ordinates in nT (BR>0 denotes spacecraft north of current sheet, BR<0 denotes spacecraft south of current sheet)
Btheta_KRTP: North-south component of the magnetic field in KRTP co-ordinates in nT. North-south field deflections characterise reconnection products
Bphi_KRTP: Azimuthal component of the magnetic field in KRTP co-ordinates in nT.
Btot: Field magnitude in nT
Range: Radial distance of Cassini from Saturn in units of Saturn radaii (1 RS = 60268 km)
Lat: Latitude of Cassini in degrees
LT: Localtime of Cassini in hours
Labels:
Null means point is not within a reconnection event
Start means point marks start of a reconnection event
Centre means point marks centre of a reconnection event
End means point marks end of a reconnection event
Event means point is within a reconnection event

I am happy for people who want to experiment with machine learning algorithms to identify events similar to those labelled in this dataset. I would ideally like to collaborate on any activities with this dataset - given the significant domain knowledge that was required to build this list. However, this is not essential. I can provide further (publicly available) Cassini data in a similar useful format to act as a test set to accompany this training set.
