Comparison of the new total local tidal strength parameter Q_trip with respect to the classic Q_A, trip parameter in Argudo-Fernández et al. (2015) for SIT isolated triplets. Upper panel: distribution of the Q_trip parameter (filled grey histogram) in comparison to the distribution of the Q_A, trip parameter (blue line histogram). Lower panel: scatter plot of the Q_trip parameter with respect to the Q_A, trip parameter (blue circles). The orange dashed line represents the y = x relation, the blue line represents the data linear regression, and the shaded light blue area indicates its corresponding error.
