RELICS: Strong Lens Model of SMACSJ0723.3-7327

Understand

We present the details of a strong lens model of SMACS J0723.3-7327, which was made public as part of the data and high level science products (HLSP) release of the RELICS HST treasury program (Reionization Lensing Cluster Survey; GO-14096, PI: Coe).

• The model products were made available on the Mikulski Archive for Space Telescopes (MAST) via 10.17909/T9SP45 in 2017.
• Here, we provide the list of constraints that were used in the HST-based RELICS lens model, as well as other information related to our modeling choices, which were not published with the data and HLSP release.
• This model was computed with Lenstool, used multiple images of 8 sources, with no spectroscopic redshifts.
