Mean values of the morphological indexes. (Because of the large number of elements, the standard error’s bar is invisible in this scale.) The line with triangles refers to the quasars already present in the LQAC-2. The line with circles refers to the new quasars in the LQAC-3 that also are found in the PPMXL catalog. Correspondingly, the line with squares refers to the new LQAC3 quasars not found in the PPMXL. The new LQAC3 population is trimmed brighter than R = 19.
