Examples
Electron Moments Data
To load and plot the electron density on March 7, 2016 measured by the FPI instrument on MMS1:
MMS> mms_load_fpi, datatype='des-moms', trange=['2016-03-07', '2016-03-08'], probe=1
MMS> tplot, 'mms1_des_numberdensity_dbcs_fast'

Ion Moments Data
To load and plot the ion density, along with the omni-directional spectra on March 7, 2016:
MMS> mms_load_fpi, datatype='dis-moms', trange=['2016-03-07', '2016-03-08'], probe=1
MMS> tplot, ['mms1_dis_numberdensity_dbcs_fast', 'mms1_dis_energyspectr_omni_avg']
