\caption{Measured and predicted lifetimes (ms) for some of the 
 levels in \ion{Fe}{x}. 
Measured values are from: 
(1) \cite{moehs_etal:01}; 
(2) \cite{trabert:04}; 
(3) \cite{trabert:96}; 
(4) \cite{trabert_etal:03};
(5) \cite{moehs_etal:00};
(6) \cite{trabert_etal:02}.

%M00: \cite{moehs_etal:00}; M01: \cite{moehs_etal:01};
%T96: \cite{trabert:96}; T02: \cite{trabert_etal:02}; 
%T03: \cite{trabert_etal:03}; T04: \cite{trabert:04}.

Note the excellent agreement between measured and 
predicted  lifetimes.
The predicted values have been calculated here
with SUPERSTRUCTURE and adjusted energies.
