\begin{table}%t1
\caption{\label{Phottab}The photometry of SN~2006aj from the Very Large Telescope (VLT), the
Liverpool Telescope (LT) and the Katzman Automatic Imaging Telescope
(KAIT), including the acquisition images for the VLT spectroscopy
(Pian et~al. \cite{Pian2006}). The date is the UT exposure
mid-time. Column $t-t_0$ refers to the time in days after the burst
trigger at $t_0 = 3$:34:30~UT of Feb.~18,~2006 (Cusumano et~al. \cite{Cusumano2006}). The third column gives measured magnitudes
which are corrected neither for extinction nor flux from the host galaxy. 
The fourth column gives the pure supernova magnitudes after correcting for 
Galactic extinction, host-galaxy flux and host-galaxy extinction. Exposure 
times are in seconds.}
