{\centering \Large \bf Low energy moments of heavy quark current correlators at four loops\\}

\medskip

\noindent The results for the expansions of the vector, axial-vector, scalar and
pseudo-scalar correlators presented in TTP09-18 are provided in the
form of {\tt FORM} readable files. For each correlator the results are
given in $\overline{\rm MS}$ and on-shell scheme in two seperate
files. We use the following notations:

\medskip

\noindent
\begin{tabular}{|c|l|}
\hline
  {\tt z} & the ratio $q^2/(4m^2)$\\\hline
  {\tt asPi} & $\alpha_s/\pi$, the strong coupling constant divided by $\pi$\\\hline
  {\tt nh} & number of heavy quarks \\\hline
  {\tt nl} & number of light quarks\\\hline
  {\tt Cf} & $C_F$, the Casimir operator of SU($n_c$) in the adjoint representation\\\hline
  {\tt Ca} & $C_A$, the Casimir operator of SU($n_c$) in the adjoint representation\\\hline
  {\tt Tf} &
  \begin{minipage}{.7\linewidth}
    $T_F$, trace normalisation for the generators $T^a$ of the
    fundamental representation
  \end{minipage}
  \\\hline
  {\tt L} & $\log \mu^2/m^2$, where $\mu$ is the 't Hooft mass\\\hline
  {\tt log2} & $\log 2$\\\hline
  {\tt z2,z3,\dots} & the values $\zeta_2,\zeta_3,\dots$ of the Riemann
  $\zeta$ function\\\hline
\end{tabular}
