""" """
======================= ==========
Spin-lattice relaxation T1 minimum
======================= ==========
Example for ``RelaxationEvaluation`` is used to get width parameter from a T1 minimum.
As a subclass of ``Relaxation`` it can also be used to calculate Relaxation times.
The basic steps are:
* Determine a T1 minimum with `nmreval.nmr.RelaxationEvaluation.calculate_t1_min`
* Calculate width parameter of a spectral density/coupling constants/... with
``RelaxationEvaluation.get_increase``
* Calculate correlation times from these values with ``RelaxationEvaluation.correlation_from_t1``
