SPEDAS provides command line and GUI access to the MMS EIS data.


EIS Data

For more complete examples, see the EIS crib sheets located in the /mms/examples/ folder.

Examples

H+ Flux

To load and plot the MMS1 EIS H+ Flux for all channels on December 15, 2015:

MMS> trange=['2015-12-15', '2015-12-16']

MMS> mms_load_eis, probes=probe, trange=trange, datatype='extof', level='l1b'

MMS> tplot, '*_extof_proton_flux_omni_spin'

He++ Flux

To load and plot the MMS1 EIS H+ Flux for all channels on December 15, 2015:

MMS> mms_load_eis, probes=probe, trange=['2015-12-15', '2015-12-16'], datatype='extof', level='l1b'

MMS> tplot, '*extof_alpha_flux_omni_spin'

Electron Data

To load and plot the MMS1 electron (electronenergy) data on December 15, 2015:

mms_load_eis, probes=probe, trange=trange, datatype='electronenergy', level = level mms_eis_pad, probe=probe, species='electron', datatype='electronenergy', data_units='flux', level = level

- plot the electron spectra tplot, ['*_epd_eis_electronenergy_electron_flux_omni_spin', '*_epd_eis_electronenergy_*keV_electron_flux_omni_pad_spin']

Burst Data

To load and plot the MMS1 EIS electron data on March 7, 2016:

load ExTOF and electron data

mms_load_eis, probes=probe, trange=trange, datatype='extof', level='l1b' mms_load_eis, probes=probe, trange=trange, datatype='electronenergy', level='l1b'

MMS> mms_load_eis, datatype='electron', trange=['2016-02-15', '2016-02-16'], probe=1, datarate='srvy'

MMS> tplot, 'mms1_epd_feeps_electron_intensity_omni_spin'

Quick Look Plots

To create EIS Quicklook Plots:
