Mean ellipticity components of spectroscopic plus red sequence satellite galaxies in a frame rotated by the position angle of the BCG, probing the alignment of satellites with the cluster BCG. BCG position angles are measured with GALFIT, while the shapes of satellite galaxies are measured with KSB. Red circles show alignments with respect to the major () and minor () axes of the BCG, while blue crosses show alignments at 45° rotations.
