 Step 3 - Doing the auto-fit

  • The aim is to minimize the distance between the traced loop and the plotted field lines.
  • Distance, d(α,h), between the traced loop and the corresponding field lines is a function of both α and h.
  • Auto-fit computes the parameter space.
  • It also gives the global minimum of d(α,h).
