Revised Lens Model for the Multiply-Imaged Lensed Supernova, "SN
  Refsdal", in MACS J1149+2223
  We present a revised lens model of MACS J1149+2223, in which the first
resolved multiply-imaged lensed supernova was discovered. The lens model is
based on the model of Johnson et al. (2014) with some modifications. We include
more lensing constraints from the host galaxy of the newly discovered
supernova, and increase the flexibility of the model in order to better
reproduce the lensing signal in the vicinity of this galaxy. The revised model
accurately reconstructs the positions of the lensed supernova, provides
magnifications, and predicts the time delay between the instances of the
supernova. Finally, we reconstruct the source image of the host galaxy, and
position the supernova on one of its spiral arms. Products of this lens model
are available to the community through MAST.
