synthesizAR.util.from_pfsspy(fieldlines, n_min=0, obstime=None, length_min=<Quantity 20. Mm>, length_max=<Quantity 3000. Mm>, name_template=None, cross_sectional_area=None)[source]#

Convert a pfsspy.fieldline.FieldLines structure into a list of Strand objects.

Parameters:

  • fieldlines (pfsspy.fieldline.FieldLines)

  • n_min (int, optional) – The minimum number of points required to keep a traced fieldline. This is often useful when trying to filter out very small or erroneous fieldlines.

  • obstime (astropy.time.Time, optional) – The desired obstime of the coordinates. Use this if the coordinates need to be at a different obstime than that of the Carrington map they were traced from.

  • length_min (astropy.units.Quantity, optional) – Minimum allowed loop length. All strands with length below this are excluded.

  • length_max (astropy.units.Quantity, optional) – Maximum allowed loop length. All strands with length above this are excluded.

  • name_template (str, optional) – Name template to use when building strands. Defaults to ‘strand_{:06d}’

  • cross_sectional_area (astropy.units.Quantity, optional) – The cross-sectional area to assign to each loop.
