\caption{Comparison of the main properties of Isolated (Is) and Perturbed (Pt) 
galaxies. The statistical parameter $z$ from the U-test is given in the third column. 
In the last three columns we give the median values for the three morphological 
bins defined in the text. The first row contains the results for the morphological 
types, the numbers in parentheses corresponding to the number of galaxies used in 
the comparison. The second row gives the fraction of galaxies with bars. The other
 rows correspond to the other properties we considered.}\label{t3}
