\tablefoot {Interaction indicators for the new sample presented in this paper. (1)~Highly disturbed velocity field. (2)~Disagreement between both sides of the rotation curve. (3)~Gaseous versus stellar major-axis misalignment. (4)~Changing position angle along major axis. (5)~Tidal Tails. (6)~High IR~luminosity. (7)~Central activity. The symbol~``+'' means that the indicator is~``on'' otherwise the symbol is~``$-$''.}
