| | Pulse Height Analysis | Particle energy spectra over a specified time interval |
| | Temperature | Particle distribution temperature |
| | Thermal Pressure | Pressure due to the thermal motion of the particles |
| | Time of Flight | Particle mass distribution determined by particle's measured momentum and time it take to travel between two sensors |
| | Velocity | Particle bulk or vector velocity |
