Figures in subfigure not aligned

I have 2 figures identical in size, I even aligned them myself in Illustrator, just to be sure, and when I put them in subfigure side by side, they are not horizontally aligned!

The worst part is, I have 2 other pictures, again the same size, and they are aligned normally. And the code is the same!! I don't know what's the problem!! Is there a way to manually shift one picture up a bit?

Here's the MWE:

%&latex

\usepackage{caption}
\usepackage{array}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}

\newcolumntype{y}[1]{>{\centering\let\newline\\\arraybackslash\hspace{0pt}}p{#1}}
\renewcommand*{\arraystretch}{1.2}

\begin{document}

\begin{figure*}[!tp]
\centering
\begin{subfigure}{0.48\textwidth}
\centering
\includegraphics[width=1.1\textwidth]{Cobalt60.eps}
\label{fig:Co}
\begin{subfigure}{0.48\textwidth}
\centering
\includegraphics[width=1.1\textwidth]{Cezij137.eps}
\label{fig:Cs}
\end{subfigure}
\caption{Lijevo: Spektar ${}^{60} \textrm{Co}$ s dvije karakteristične zrake na 1173.237 keV i 1332.501 keV. Desno: Spektar ${}^{137} \textrm{Cs}$ s karakterističnom zrakom na 661.657 keV. Na manjoj slici je uvećan Comptonov rub smješten oko 550-og kanala.}
\label{fig:Spektripoz1}
\end{figure*}

\begin{figure*}[!tp]
\centering
\begin{subfigure}{0.48\textwidth}
\centering
\includegraphics[width=1.1\textwidth]{Barij133.eps}
\label{fig:Ba}
\begin{subfigure}{0.48\textwidth}
\centering
\includegraphics[width=1.1\textwidth]{fit.eps}
\end{subfigure}
\caption{Lijevo: Spektar ${}^{133} \textrm{Ba}$. Barijev spektar ima nekoliko karakterističnih vrhova, no uzimamo samo najintenzivniji vrh. Desno: Kalibracijski pravac.}
\label{fig:Spektripoz2}
\end{figure*}

\end{document}


And here are the pictures (.eps format):

The second right picture is lower than the left, and the first pictures are perfectly aligned...

Looking at the code it is obvious what the difference between the two floats is: the labels! Since you don't have sub-captions, remove the \label commands for them, and the alignment problem disappears.
Nonono, this happens. But maybe @AxelSommerfeldt might have a look into this, as the \label seems to leak something into the float. –  mafp Mar 13 '13 at 16:34
