[Tex/LaTex] Turn off superscript when all authors have same affiliation (elsarticle)

elsarticletitles

I'm using the elsarticle class, which adds superscripts to link the author to their affiliation. However, all of the authors for my paper have the same affiliation, so it looks a little weird for them all to have the superscript "a" (as shown below).

\documentclass{elsarticle}

\author[su]{Jane Doe\corref{cor1}}
\ead{jdoe@someuniversity}
\author[su]{Joe Bloggs}
\ead{jbloggs@someuniversity}

\cortext[cor1]{Corresponding author}

\address[su]{Department of Underwater Basket-weaving, Some University}

\begin{document}

\maketitle

\end{document}

enter image description here

Is there a way to turn this off? I experimented with leaving off the [su] tags, but that results in all the authors getting an asterisk marking them as corresponding authors!

EDIT: Here's a complete example:

\documentclass[preprint,12pt]{elsarticle}

\journal{Some Journal}

\begin{document}

\begin{frontmatter}

\title{My Article}

\author[su]{Jane Doe\corref{cor1}}
\ead{jdoe@someuniversity}
\author[su]{Joe Bloggs}
\ead{jbloggs@someuniversity}

\cortext[cor1]{Corresponding author}

\address[su]{Department of Underwater Basket-weaving, Some University}

\begin{abstract}

Abstract

\end{abstract}

\begin{keyword}
test
\end{keyword}

\end{frontmatter}

\section{Introduction}

Blah blah blah

\end{document}
\endinput

Best Answer

Here's a way to achieve your output:

enter image description here

\documentclass{elsarticle}

\author{Jane Doe\corref{cor1}}
\ead{jdoe@someuniversity}
\author{Joe Bloggs\corref{}}
\ead{jbloggs@someuniversity}

\cortext[cor1]{Corresponding author}

\address{Department of Underwater Basket-weaving, Some University}

\begin{document}

\maketitle

\end{document}

Providing an empty \corref{} to the non-corresponding author removes the unwanted asterisk.
