NOTE plag is superseded by fqlag which has a more stable implementation. Please use that instead.

This is an implementation of the method used in Zoghbi+2013 paper (Astrophysical Journal; 2013. 777. 24Z) to calculate lags in the frequency domain from unevenly-sampled light curves.

INSTALL

• install cython by doing:

pip install cython

• compile plag make setup

• run test to make sure things compiled properly make test

• See the following python notebook for usage example.
