triqs_ctseg::precompute_fprefactor
==================================

*#include <triqs_ctseg.hpp>*

.. rst-class:: cppsynopsis

      class  :red:`precompute_fprefactor`

 Object which precomputes the prefactor :math:`I_{o_1}(\tau)` for the improved
 estimator
:math:`I_{o_1}` is used in the computation of the improved estimator
:math:`F_{o_1}(\tau)`. It is defined as:


.. math::
		I_{o_1}(\tau) = \int_0^\beta d\bar{\tau} \sum_{o_2}
\hat{\mathcal{U}}_{o_1,o_2}(\tau-\bar{\tau}) n_{o_2}(\bar{\tau})

..
 This object
models the concept of mc_generic auxiliary precomputation.

.. note::
    In the measurement all times are accessed for a given orbital and not
vice versa; Storage in vector of maps instead of map of vectors keeps the
individual maps small
