Fraction of satellites in our sample of supermassive galaxies. Disks and spheroids are shown as blue squares and red circles. The dashed black line shows the mean fraction of satellites within the massive regime. Errors correspond to one sigma binomial errors as stated in Cameron (2011), while the gray shaded area corresponds to three sigma binomial errors for the whole sample. We can see that although disks tend to have a mild tendency to be satellites, the fractions of satellites for disks and spheroids are comparable within one sigma.
