This algorithm provides a method for making a rotating reference frame transformation, which provides a useful method of visualising high frequency signals.
Since the transformation leaves a comparatively low frequency signal, the data can readily be rebinned to improve counting statistics - this is particularly
useful during an experiment to provide an early check on the form of the measured signal. Data analysis (for example least squares fitting) to study the
form of the signal relaxation can be completed in either the laboratory or rotating reference frame according to preference.
This algorithm is frequently run after making a phase quadrature transformation using the algorithm :ref:`algm-PhaseQuad`. Both algorithms are fully described in the
article by T.M. Riseman and J.H. Brewer [Hyp. Int., 65, (1990), 1107].
