Graphics, Figures & Tables ⇒ subcaption | Top-aligned Sub-figures

[dcernst]

I have a few figures that would look much better if I could get the corresponding subfigures to be aligned along their tops. I'm currently using the caption and subcaption packages. If possible, I'd prefer a solution that I can apply locally (as opposed to every figure), but easily. Here is a minimal example of my current situation:

Code: Select all

\documentclass[11pt]{amsart}
\usepackage[margin=1in]{geometry}
\usepackage{graphicx}
\usepackage{caption}
\usepackage[labelformat=simple,labelfont={}]{subcaption}

\renewcommand\thesubfigure{(\alph{subfigure})}

\begin{document}

\begin{figure}[!ht]
\subcaptionbox{\label{Fig150}}{\includegraphics[scale=.95]{Fig150}}
\qquad
\subcaptionbox{\label{Fig151}}{\includegraphics[scale=.95]{Fig151}}
\qquad
\subcaptionbox{\label{Fig152}}{\includegraphics[scale=.95]{Fig152}}
\subcaptionbox{\label{Fig153}}{$2^{c}\ \begin{tabular}[c]{@{}c@{}}
\includegraphics[scale=.95]{Fig153}
\end{tabular}$}
\qquad
\subcaptionbox{\label{Fig154}}{\includegraphics[scale=.95]{Fig154}}
\qquad
\subcaptionbox{\label{Fig155}}{\includegraphics[scale=.95]{Fig155}}
\caption{}\label{Fig150--Fig155}
\end{figure}

\end{document}

I've attached the corresponding PDF.
