Exact column labels and their descriptions for the catalogs.

Emissive catalog column label	Emissive source catalog description
`index`	Integer index where the catalog is sorted in descending order of 150 GHz signal-to-noise.
`iau_name`	IAU name follows the convention of a catalog prefix (“SPT-S”), R.A., and Dec. in sexagesimal format.
`ra`	Right ascension (J2000) of the source in the highest detection band in degrees.
`dec`	Declination (J2000) of the source in the highest detection band in degrees.
`sn95`	95 GHz signal-to-noise ratio of the detection. Values below 5σ are pulled from the signal-to-noise map when the source was detected above 5σ in another band.
`sn150`	150 GHz signal-to-noise ratio of the detection.
`sn22 0`	220 GHz signal-to-noise ratio of the detection.
`s95`	Flux at 95 GHz in mJy converted from CMB temperature. Fluxes are from forced-photometry in bands where the source was not detected > 5σ.
`s150`	Flux at 150 GHz in mJy.
`s220`	Flux at 220 GHz in mJy.
`alpha95`	Spectral index between 95 and 150 GHz ( $α_{150}^{95}$ $\alpha^{95}_{150}$ , Eq. 16).
`erroralpha95`	The error on $α_{150}^{95}$ $\alpha^{95}_{150}$ propagated from the flux errors.
`alpha220`	Spectral index between 150 and 220 GHz ( $α_{220}^{150}$ $\alpha^{150}_{220}$ , Eq. 16).
`erroralpha220`	The error on $α_{220}^{150}$ $\alpha^{150}_{220}$ propagated from the flux errors.
`thumb`	“Coadd[frame name]” if the source is one of the specially treated bright source thumbnails (Sect. 3.5), 0 (for False) otherwise.^a
`extended`	1 for True if flagged according to the methods described in Sect. 6.3, 0 for False if pointlike.
`edfs_flag`	1 for True if inside the EDF-S, 0 for False if outside the EDF-S.
`dsfg_flag`	1 for True if flagged as a DSFG candidate (see Sect. 6.3), 0 for False otherwise.
`counterparts`	External catalog counterparts according to Sect. 6.4 where 1 = radio (ASKAP low, mid, or high), 2 = infrared (WISE), and 3 = millimeter (SPT-SZ).
Cluster catalog column label	Cluster catalog description
`iau_name`	Name of the SPT cluster candidate. The IAU name follows the convention of a catalog prefix (“SPT-CL”), R.A., and Dec. in sexagesimal format.
`ra`	Right ascension (J2000) of the tSZ detection in degrees.
`dec`	Declination (J2000) of the tSZ detection in degrees.
`xi`	SPT cluster detection significance (see Sect. 4.4).
`theta_core`	ß-profile core radii used in the matched filter corresponding to xi.
`redshift`	Redshift of associated optical/infrared galaxy overdensity. If no associated redshift is available, the column value is −1.
`redshift_unc`	Redshift uncertainty if available, −1 otherwise.
`specz`	Equals 1 if redshift is spectroscopic.
`m500`	Mass M_500C in units of 10¹⁴M_⊙/h₇₀.
`m500_uerr`	1 sigma upper uncertainty on mass.
`m500_lerr`	1 sigma lower uncertainty on mass.
`lambda`	Richness of associated optical/infrared galaxy overdensity.
`lambda_unc`	Richness uncertainty.
`fcont`	Integrated optical/infrared contamination for richness > lambda (f _cont, see Sect. 4.4.1).
`edfs_flag`	1 for True if inside the EDF-S, 0 for False if outside the EDF-S.
`los`	Equals 1 if there is a secondary structure along the LOS with f_cont <0.2.
`redshift2`	Redshift secondary structure.
`redshift2_unc`	Redshift uncertainty secondary structure.
`lambda2`	Richness secondary structure.
`lambda2_unc`	Richness uncertainty secondary structure.
`fcont2`	Integrated optical/infrared contamination for richness > lambda2 for secondary structure.
`unconfirmed_redshift`	Redshift for LOS overdensity below confirmation threshold (only provided when candidate is not confirmed).
`unconfirmed_redshift_unc`	Redshift uncertainty for LOS overdensity below confirmation threshold.
`unconfirmed_lambda`	Richness of most significant LOS galaxy overdensity when candidate is not confirmed.
`unconfirmed_lambda_unc`	Richness uncertainty for LOS overdensity below confirmation threshold.
`unconfirmed_fcont`	Integrated optical/infrared contamination for LOS overdensity below confirmation threshold.^b

Notes. ^(a)The bright source’s label in the thumb column comes from the center of the thumbnail and is therefore not guaranteed to equate to the IAU name of the source, in the event of the source’s recorded location shifting from the precise center of the thumbnail.

^(b)For unconfirmed cluster candidates (f_cont > 0.2), we provide properties of the most significant galaxy overdensity detected along the LOS, but do not report masses for these structures.
