\caption{Interaction Indicators.  Description of the columns: 
(1) Highly disturbed velocity field.  
(2) Disagreement between both sides of the rotation curve. 
(3) Central double nuclei.  
(4) Double kinematic gas component. 
(5) Changing position angle (PA) along major axis~(MA).  Rotation of external isophotes.  
(6) Gaseous vs stellar MA misalignment.  The indicator is "on'' if the ranges of values do not intersect. 
(7) Tidal Tail, shell, filaments.  
(8) High $L_{\rm IR}$.  
(9) Central activity.  
The symbol "+'' means that the indicator is "on'' otherwise the
symbol is "--''. The symbol $"\times''$ means that the data do not
allow measurements.\label{tab5}}
