Notes. Column 2 reports the number of physically related galaxies (the spread of velocities for the individual galaxies is about 150 km s-1) in a field of 1 square degree around each galaxy in our sample. Column 3 is the slope of the outer halo surface brightness profiles, obtained by performing a power-law fit in the region of the outer envelope derived from the two-component model, that is between Rtr and the last measured point.
