This page provides data products associated with the point-source catalog from 771 square degrees of SPT data described in Mocanu et al (2013). The data products include the full three-band source catalog (down to a significance threshold of 4.5 sigma), the differential number counts in each band (total and divided into synchrotron- and dust-dominated counts), the cumulative number counts in each band, and covariance matrices for the synchrotron-dominated number counts and the dust-dominated number counts in each band. For the point source catalog, the column descriptions are: 1. Source ID: the IAU designation for the SPT-detected source.2. RA: right ascension (J2000) in degrees. 3. DEC: declination (J2000) in degrees. 4. S/N (95 GHz): detection significance (signal-to-noise ratio) in the 95 GHz band. 5. Sraw (95 GHz): raw flux (uncorrected for flux boosting) in the 95 GHz band. 6. Sbest (95 GHz): median value of de-boosted flux at 95 GHz. 7. dSup (95 GHz): upper error bar (1-sigma normal equivalent) of de-boosted flux at 95 GHz. 8. dSdown (95 GHz): lower error bar (1-sigma normal equivalent) of de-boosted flux at 95 GHz. 9. S/N (150 GHz): detection significance (signal-to-noise ratio) in the 150 GHz band. 10. Sraw (150 GHz): raw flux (uncorrected for flux boosting) in the 150 GHz band. 11. Sbest (150 GHz): median value of de-boosted flux at 150 GHz. 12. dSup (150 GHz): upper error bar (1-sigma normal equivalent) of de-boosted flux at 150 GHz. 13. dSdown (150 GHz): lower error bar (1-sigma normal equivalent) of de-boosted flux at 150 GHz. 14. S/N (220 GHz): detection significance (signal-to-noise ratio) in the 150 GHz band. 15. Sraw (220 GHz): raw flux (uncorrected for flux boosting) in the 220 GHz band. 16. Sbest (220 GHz): median value of de-boosted flux at 220 GHz. 17. dSup (220 GHz): upper error bar (1-sigma normal equivalent) of de-boosted flux at 220 GHz. 18. dSdown (220 GHz): lower error bar (1-sigma normal equivalent) of de-boosted flux at 220 GHz. 19. alpha95150,raw: estimate (from the raw flux in each band) of the 95 GHz-150 GHz spectral index alpha. 20. alpha95150,best: median value of spectral index. 21. d_alpha95150,up: upper error bar (1-sigma normal equivalent) of spectral index. 22. d_alpha95150,down: lower error bar (1-sigma normal equivalent) of spectral index. 23. alpha150220,raw: estimate (from the raw flux in each band) of the 150 GHz-220 GHz spectral index alpha 24. alpha150220,best: median value of spectral index. 25. d_alpha150220,up: upper error bar (1-sigma normal equivalent) of spectral index. 26. d_alpha150220,down: lower error bar (1-sigma normal equivalent) of spectral index. 27. P(alpha > 1.5): fraction of the spectral index posterior probability distribution above the threshold value of 1.5. A higher value of P means the source is more likely to be dust-dominated. 28. Type: source classification (synchrotron- or dust-dominated). 29. Extended flag: flag for extended sources. 30. External counterparts: external catalogs wherein a source has a match with an offset smaller than the chosen association radius. We choose an association radius of 1 arcminute for all catalogs except WISE, where we use 0.5 arcminutes. For the differential number counts as a function of flux in each band, the column descriptions are: 1. Flux range [low]: Low end of flux bin in which counts were estimated. In units of Jy.2. Flux range [high]: High end of flux bin in which counts were estimated. In units of Jy. 3. dN/dS total, central: Central value of differential counts (in units of number per square degree per Jy) for all sources detected in the band. 4. dN/dS total, lower error bar: 1-sigma lower error bar for differential counts (in units of number per square degree per Jy) for all sources detected in the band. 5. dN/dS total, upper error bar: 1-sigma upper error bar for differential counts (in units of number per square degree per Jy) for all sources detected in the band. 6. dN/dS synchrotron, central: Same as [3] for synchrotron-dominated sources detected in the band. 7. dN/dS synchrotron, lower error bar: Same as [4] for synchrotron-dominated sources detected in the band. 8. dN/dS synchrotron, upper error bar: Same as [5] for synchrotron-dominated sources detected in the band. 9. dN/dS dust, central: Same as [3] for dust-dominated sources detected in the band. 10. dN/dS dust, lower error bar: Same as [4] for dust-dominated sources detected in the band. 11. dN/dS dust, upper error bar: Same as [5] for dust-dominated sources detected in the band. 12. dN/dS dust (IRAS removed), central: Same as [3] for dust-dominated sources detected in the band, excluding IRAS-FSC counterparts. 13. dN/dS dust (IRAS removed), lower error bar: Same as [4] for dust-dominated sources detected in the band, excluding IRAS-FSC counterparts. 14. dN/dS dust (IRAS removed), upper error bar: Same as [5] for dust-dominated sources detected in the band, excluding IRAS-FSC counterparts. 15.
