Detailed Description

Temporal phase curve model class.

This class implements a temporal variation based on the phase \(\Phi(t)\) that is computed using

\[ \Phi(t) = \Phi_0 + f(t-t_0) + \frac{1}{2}\dot{f} (t-t_0)^2 + \frac{1}{6}\ddot{f} (t-t_0)^3 \]

where \(t_0\) is a reference time, \(\Phi_0\) is the phase at the reference time, \(f\) is the variation frequency at the reference time, \(\dot{f}\) is the first derivative of the variation frequency at the reference time, and \(\ddot{f}\) is the second derivative of the variation frequency at the reference time.

The temporal variation is then computed using

\[ S_{\rm t}(t) = r(\Phi(t)) \times {\tt m\_norm} \]

where \(r(\Phi(t))\) is the rate defined by linear interpolation between the nodes in a FITS file, and \({\tt m\_norm}\) is a normalisation constant.
