### Overview

This PlugIn separates a (plasma) velocity into a component along and a component perpendicular to the magnetic field. The plugin works sample for sample.

### Input data

Required inputs are :
- Bfield - vector time series with maqgnetic field
- Plasma velocity - vector time series with plasma velocity

The magnetic field is automatically joined to the plasma data.

### Outputs

Output quantities are:
- v_perp - plasma velocity component perpendicular to the magnetic field

- v_perp - plasma velocity component along the magnetic field

### Bugs/Caveats

None known.

### Other MPE/ISSI PlugIns

- Generic residue analysis of conservation laws
- Vector calculator/ Curlometer
- DeHoffmann-Teller analysis
- Solar wind utility. Calculates IMF clock angle, energy input, dynamic pressure etc.
- EDI filter utility
- Separate plasma velocity into paralell and perpendicular components
- Plasma calculator. Calculates plasma beta, magnetic pressure, resistivity inertial lengths etc.
- Modify, mask and manipulate components of a vector
- Construct a matrix time series from scalar time series
