Notes. Parameters of the elliptical shape of the GCS for the red and blue populations, in the case of a variable (g′−i′)₀ limit between the two populations. The columns report the coordinates 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 were calculated via the Bootstrap method.
