Abstract
We present a new high-precision strong lensing model of PLCK G287.0+32.9, a massive lens galaxy cluster at z = 0.383, based on 153 spectroscopically and photometrically selected member galaxies and 47 secure multiple images of 12 background multiply-lensed sources. The total mass distribution derived from our model shows this cluster to be a very prominent gravitational lens with the third biggest Einstein radius of θE =43.4′′ ± 0.1′′ known to date.
