CHECK_Hund.dat
--------------

This file is outputted to check the input of the Hund couplings
:math:`J_{ij}^{\rm Hund}`,

.. math:: -\sum_{i,j}J_{ij}^{\rm Hund} (n_{i\uparrow}n_{j\uparrow}+n_{i\downarrow}n_{j\downarrow}).

An example of the file format is as follows.

::

    i=0 isite1=1 isite2=2 tmp_V=0.250000 
    i=1 isite1=2 isite2=3 tmp_V=0.250000 
    i=2 isite1=3 isite2=4 tmp_V=0.250000 
    i=3 isite1=4 isite2=5 tmp_V=0.250000 
    i=4 isite1=5 isite2=6 tmp_V=0.250000
