FEEPS quicklook plot in SPEDAS

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

Prior to using these data, please read the FEEPS Release Notes:

https://lasp.colorado.edu/galaxy/display/mms/FEEPS+Release+Notes


FEEPS Data

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

Examples

Electron Data

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

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

MMS> tplot, 'mms1_epd_feeps_electron_intensity_omni_spin'

Ion Data

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

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

MMS> tplot, 'mms1_epd_ion_electron_intensity_omni_spin'

Quicklook Plots

To create FEEPS Quicklook plots use the crib mms_load_feeps_crib_qlplots.pro This crib will load electron and ion data. It shows the user how to use mms_feeps_pad to calculate the pitch angle distributions. In addition spacecraft ephemeris data, FGM B-field data and data availability are loaded and displayed.

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

FEEPS Sector Spectrograms

Examples

Sector-Time Spectrograms, No Sun Contamination Removed

To create sector spectrograms of FEEPS data on January 20, 2016:

MMS> mms_load_feeps, trange=['2016-01-20/19:50', '2016-01-20/19:55'], probe=1, data_rate='brst', level='12', /time_clip

MMS> feeps_sector_spec, probe=1, data_rate='brst'

MMS> tplot, ['mms1_epd_feeps_bottom_electron_count_rate_sensorid_3_sectspec', $ 'mms1_epd_feeps_bottom_electron_count_rate_sensorid_4_sectspec', $ 'mms1_epd_feeps_bottom_electron_count_rate_sensorid_5_sectspec', $ 'mms1_epd_feeps_bottom_electron_count_rate_sensorid_10_sectspec', $ 'mms1_epd_feeps_bottom_electron_count_rate_sensorid_11_sectspec']

Sector-Time Spectrograms, With Sun Contamination removed

To create sector spectrograms of FEEPS data on January 20, 2016:

MMS> mms_load_feeps, trange=['2016-01-20/19:50', '2016-01-20/19:55'], probe=1, data_rate='brst', level='12', /time_clip

MMS> feeps_sector_spec, probe=1, data_rate='brst', /remove_sun

MMS> tplot, ['mms1_epd_feeps_bottom_electron_count_rate_sensorid_3_sun_removed_sectspec', $ 'mms1_epd_feeps_bottom_electron_count_rate_sensorid_4_sun_removed_sectspec', $ 'mms1_epd_feeps_bottom_electron_count_rate_sensorid_5_sun_removed_sectspec', $ 'mms1_epd_feeps_bottom_electron_count_rate_sensorid_10_sun_removed_sectspec', $ 'mms1_epd_feeps_bottom_electron_count_rate_sensorid_11_sun_removed_sectspec']
