  The analytic continuations (ACs) of the double variable Horn $H_1$ and $H_5$
functions have been derived for the first time using the automated symbolic
$\textit{Mathematica}$ package $\texttt{Olsson.wl}$. The use of Pfaff-Euler
transformations have been emphasised to derive AC to cover regions which are
otherwise not possible. The corresponding region of convergence (ROC) is
obtained using its companion package $\texttt{ROC2.wl}$. A
$\textit{Mathematica}$ package $\texttt{HornH1H5.wl}$, containing all the
derived ACs and the associated ROCs, along with a demonstration file of the
same is made publicly available in https://github.com/souvik5151/Horn_H1_H5 .
