Description

For the full 3-sigma source catalog at 1.4 and 2.0 mm from Vieira et al. (2009):
Columns in the file 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 (2.0 mm): detection significance (signal-to-noise ratio) in the 
      2.0 mm band.
   5. Srawsup (2.0 mm): raw flux (uncorrected for flux boosting) in the 
      2.0 mm band.
   6. Sbest (2.0 mm): median value of de-boosted flux at 2.0 mm.
   7. dSup (2.0 mm): upper error bar (1-sigma normal equivalent) of 
      de-boosted flux at 2.0 mm.
   8. dSdown (2.0 mm): lower error bar (1-sigma normal equivalent) of 
      de-boosted flux at 2.0 mm.
   9. S/N (1.4 mm): detection significance (signal-to-noise ratio) 
      in the 1.4 mm band.
  10. Sraw (1.4 mm): raw flux (uncorrected for flux boosting) 
      in the 1.4 mm band.
  11. Sbest (1.4 mm): median value of de-boosted flux at 1.4 mm.
  12. dSups (1.4 mm): upper error bar (1-sigma normal equivalent) 
      of de-boosted flux at 1.4 mm.
  13. dSdown (1.4 mm): lower error bar (1-sigma normal equivalent) 
      of de-boosted flux at 1.4 mm.
  14. alpharaw: estimate (from the raw flux in each band) of the 
      2.0 mm-1.4 mm spectral index alpha
  15. alphabest: median value of spectral index.

      of spectral index.

      equivalent) of spectral index.
  18. P(alpha > 1.66): fraction of the spectral index posterior 
      probability distribution above the threshold value of 1.66. 
      A higher value of P means the source is more likely to be dust-dominated.

      the nearest source in the 36 cm (843 MHz) Sydney University Molongolo Sky Survey.

      from the nearest source in the ROSAT All-Sky Survey (RASS) 
      Bright Source Catalog or Faint Source Catalog.
  22. Nearest IRAS source: angular distance (in arseconds) 
      from the nearest source in the IRAS Faint-Source Catalog.
