\caption[]{Table of longitudinal magnetic field measurements. Columns 1, 2 and 3 
indicate the number, HJD and phase (with $P$ = 3.638833 d) of each measurement 
respectively. Columns 4 and 5 give the
longitudinal field measurement and its error bar. Columns 6 and 7 give the null polarisation 
and its error bar.}
