THEMIS Particle Spectrograms

Energy, phi, and theta spectrograms from THEMIS ESA ion data.

Angular and energy spectrograms can be produced from THEMIS ESA and SST particle data. Spectrograms (or spectra) are produced after selecting a spacecraft, data type, and time range. The data are then averaged across the non-selected dimensions and plotted across time. Magnetic field aligned spectra can also be generated.

For command line usage see:

SPEDAS Plugin

SPEDAS GUI plugin for producing THEMIS particle spectrograms

Particle spectrograms can be created from the SPEDAS GUI.

SPEDAS> spd_gui

From the File menu select Load Data then select the THEMIS Derived Spectra tab. Most parameters can be edited from this interface, however some remain command line only. Multiple probes and data types may be selected. All selected output types will be created for each probe/datatype combination. Required support data will be loaded automatically.
