The positions of those sources also detected in 8~April~2008 coincide within the errors ($\la$0.5~mas) with all of~them. \\ $^{{b}}$ The uncertainty in the reported flux density for the detected compact components corresponds to 1$\sigma$, where $\sigma$ was determined by adding in quadrature the off-source rms in each image and a~5\% of the local maxima, to~conservatively account for possible inaccuracies in the eEVN~\mbox{calibration}. \\ $^{{c}}$ We define the significance of the flux density variability between the two consecutive epochs as $V = \mid S_{\rm Dec} - S_{\rm Apr}\mid / \sqrt{\sigma_{\rm Dec}^2+ \sigma_{\rm Apr}^2}$, where $S_{\rm Apr}$ and $\sigma_{\rm Apr}$ ($S_{\rm Dec}$ and $\sigma_{\rm Dec}$) are the values in Cols.~5 and~6 (7~and~8), respectively. \\ $^{{d}}$ Source names are given in right ascension order, except for the five components reported previously (A0~through A4) by \citep{neff04}. \end{table}
