A digital version of Table 1 from the published article is provided to facilitate data analysis. Table 1 presents a summary of the 83 SCALE systems, with each row corresponding to an individual cluster and reporting aggregated cluster properties. The table includes the principal quantities derived in this work, such as

Columns description #

Columns prefixed with `sp` are drawn from S-PLUS DR5 (E. V. Lima et al. 2026, in preparation), while those prefixed with `ls` originate from Legacy Survey DR10[^legacy]. Columns prefixed with `lit` originate from redshift compilation from the literature[^erik-redshifts]. Columns without these prefixes were derived in this work. All magnitudes are reported in the AB system, and the S-SPLUS magnitudes included in the catalog are only the auto-aperture values.
