FEEPS quicklook plot in SPEDAS

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


For more information on the EPD-FEEPS instrument, please see the EPD Data Products Guide:

https://lasp.colorado.edu/mms/sdc/public/datasets/epd/ (EPD Data Products Guide 13Apr16 v4)


FEEPS Data

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

Examples

Electron Data

To load and plot the MMS1 FEEPS electron data on March 7, 2016: <syntaxhighlight lang="idl"> MMS> mms_load_feeps, datatype='electron', trange=['2016-02-15', '2016-02-16'], probe=1, data_rate='srvy'

MMS> tplot, 'mms1_epd_feeps_srvy_l2_electron_intensity_omni_spin' </syntaxhighlight>

Ion Data

To load and plot the MMS1 FEEPS electron data on March 7, 2016: <syntaxhighlight lang="idl"> MMS> mms_load_feeps, datatype='ion', trange=['2016-02-15', '2016-02-16'], probe=1, data_rate='srvy'

MMS> tplot, 'mms1_epd_feeps_srvy_l2_ion_intensity_omni_spin' </syntaxhighlight>
