Compare IDL code to python code for creating a spectrogram from THEMIS data.
IDL code: SPEDAS
trange = ['2010-02-13', '2010-02-14'] probe = 'b' thm_load_esa, probe=probe, trange=trange, datatype='peef_density peef_velocity_dsl peef_en_eflux' tplot, ['thb_peef_density', 'thb_peef_velocity_dsl', 'thb_peef_en_eflux']
Python code: pySPEDAS
import pyspedas import pytplot # Get data trange = ['2010-02-13', '2010-02-13'] probe = 'b' var = ['thb_peef_density', 'thb_peef_velocity_dsl', 'thb_peef_en_eflux'] pyspedas.themis.esa(probe=probe, trange=trange, varnames=var) # Set plot options pytplot.options(var[1], 'ytitle', var[1]) pytplot.ylim(var[1], -700, 800) pytplot.options(var[2], 'colormap', 'jet') pytplot.options(var[2], 'ylog', True) pytplot.options(var[2], 'zlog', True) pytplot.options(var[2], 'ytitle', var[2]) pytplot.ylim(var[2], 1.5, 50000.0) # Plot pytplot.tplot(var)
