ion_dist_single

heliopy.data.helios.ion_dist_single(probe, year, doy, hour, minute, second, remove_advect=False)

Read in ion distribution function.

Parameters:
  • probe (int, string) – Helios probe to import data from. Must be 1 or 2.
  • year (int) – Year
  • doy (int) – Day of year
  • hour (int) – Hour
  • minute (int) – Minute.
  • second (int) – Second
  • remove_advect (bool, optional) –

    If False, the distribution is returned in the spacecraft frame.

    If True, the distribution is returned in the solar wind frame, by subtracting the spacecraft velocity from the velcoity of each bin. Note this significantly slows down reading in the distribution.
Returns:

dist – 3D ion distribution function
Return type:
