Phase Weighted Stack
--------------------

Steps to perform the phase weighted stack:

#.

.. math::

    S(t)=s(t)+i H(s(t))=A(t) \exp [i \Phi(t)]

.. math::

    c(t)=\frac{1}{N}\left|\sum_{j=1}^{N} \exp \left[i \Phi_{j}(t)\right]\right|

.. math::

    g(t)=\frac{1}{N} \sum_{j=1}^{N} s_{j}(t)\left|\frac{1}{N} \sum_{k=1}^{N} \exp \left[i \Phi_{k}(t)\right]\right|^{v}
