Notes. Parameters of the elliptical shape of the GCS for the total, red, and blue populations. The columns report the right ascension and declination of the center of the ellipse (RA and Dec), the major and minor axis (a and b), the position angle (PA), and the ellipticity (e). The errors on the parameters are calculated via the Bootstrap method.
