\caption{\label{ies_tab}Isolated emission features detected in the individual data sets,
which here appear sorted with increasing equivalent width. Columns~2 to 4 give 
basic parameters of the systems, i.e.\ the period, the inclination,
the mass ratio $q = M_2/M_1$, and the (normal) outburst recurrence time, except
for RZ Leo and WX Cet, which show only superoutbursts. These parameters were 
taken from the Ritter \& Kolb (\cite{rittkolb98}) catalogue except where 
indicated. Columns 5 and 6 contain the data set specific information on the 
equivalent width of the H$\alpha$ emission line and the accretion state during 
the observations (d = decline, q = quiescence), respectively. The 
$x$-velocities in Cols.\ 7 and 8 refer to the emission maxima in the 
respective halves of the Doppler maps, other emission regions are denoted by 
their identification. 
The presence of a feature is indicated by "$+$'', its absence by
"$-$'', uncertain ones by "?'', and very uncertain ones by "??''.}
