Here:
  xsm, ysm, and zsm: Satellite location in SM coordinates in Re (1 RE=6378.14 km)
  mlt: Magnetic local time in hours
  mlat: Magnetic latitude in degrees
  L_dip - L-shell calculated from R and MLAT assuming a dipole magnetic field
  fce_model: Model electron cyclotron frequency in kHz.
             T96 model is used for the background magnetic field, which
             requires the solar wind dynamic pressure, IMF Bz, and the DST index as input.
             If these parameters were not available, default values of solar wind pressure
             of 2.1 nPa, IMF Bz of 0 nT, and DST of -10 nT were used
  electron_density: Electron density in 1/cm^3
  fpe: Electron plasma frequency (kHz) from fits
  doy: day of year number
  type: 1:Upper Hybrid, 2:Z-Mode, 3:Continuue Edge
  num_n+1/2: number of n+1/2 harmonics recognized by automatic routine
  fce_n+1/2: electron cyclotron frequency (kHz) from the spacing of n+1/2 harmonics
  sd_n+1/2: standard deviation (kHz) of fce_n+1/2 based on individual frequencies
  am: 1: automatic fit, 2: manual fit
