For each cluster candidate we provide the position, the highest detection significance in filtered SPT maps (and the core radii corresponding to the detection), redshift information and, for each confirmed cluster, a mass estimate. Where available we additionally provide an optical richness from the RM algorithm in "scanning" mode centered at the SPT location, the probability of false association with the RM targeted galaxy overdensity, flag if the estimated radio contamination exceeds 10% of the SZ signal, flag identified strong gravitational lenses, and---if applicable---provide lierature references for the strong lenses and spectroscopic redshifts. Masses are determined using the best-fit ξ-mass scaling relation for a flat LCDM cosmology with Ωm = 0.3, h=0.7 and σ8 = 0.8.

The key to the imaging/redshift source is as follows:

(1) Pan-STARRS1, (2) PISCO, (3) DES, (4) Magellan/Fourstar, (5) Spitzer/IRAC, (6) WISE,
(7) literature photometric redshift, (8) spectroscopic redshift.
