Fig. 1.

Optical images of the two target BCGs. Left: i-band SDSS DR12 image centered at the coordinates of 3C 244.1. Right: i-band Pan-STARRS1 image centered at the coordinates of SDSS J161112.65+550823.5. Both images are 24″ × 24″ in size. At the bottom left of each figure a 5″ segment is shown, along with its corresponding value in physical units, at the redshift of the BCGs.
