Detailed Description

Construct derivative meson sequential sources.

These operators come from Liao and Manke, hep-lat/0210030 . There are a few variants of derivatives. They are

$D_i = s_{ijk}\nabla_j\nabla_k$ $B_i = \epsilon_{ijk}\nabla_j\nabla_k$ $\nabla_\mu f(x) = U_\mu(x)f(x+\mu) - U_{-\mu}(x)f(x-\mu)$

where

$s_{ijk} = |\epsilon_{ijk}|$ $S_{\alpha jk} = 0\quad j\ne k, S_{111}=S_{222}=1, S_{122}=S_{233}=-1$

The sequential sources return
