  • "Set Range" does not always work, because the lsqf runs into the limit of the range (done by lmfit)
  • On initial fit: Add heuristic fitting
    • fit converges better, when amplitude of starting parameters is above data amplitude (done by lmfit)
    • if F1 gets stuck at 1, set F1 to 0.75 and fit again (maybe try to fix F1 once and the fit again)

  • try to sort diffusion times "tautrip < tau1 < tau2" (#110)

  • check if parameters run into the boundaries of the valid regime, reset and refit (this is done by lmfit)
