Class MEAL::PhaseGradients

template<typename T>
class PhaseGradients : public MEAL::Univariate<T>

Multiple phase gradients parameterized by their slopes.

When performing Measurement Equation Template Matching (METM), multiple observed pulse profiles are fit to a single well-calibrated standard template profile. In this case, there are two options:

1. Assume that the ephemeris is good and model all observations using a single phase offset between them and the standard profile; in this case, this class stores and is parameterized by a single gradient (and offset).

WARNING: A single offset also assumes that all observations also have the same number of phase bins. This should be checked!

1. Model each observation using an unique phase offset between the observation and the standard profile; in this case, this class stores and is parameterized by multiple gradients (and offsets).

This class is a template so that it can be used as a Jones matrix (Complex2) or as a complex-valued scalar (Complex).
