  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.
The image plane RMS was 0".58.
