FOREGROUND GALACTIC EXTINCTION for SDSS J021723.29+020021.0 (Back to INDEX)

Galactic Extinction from the Schlafly & Finkbeiner 2011, Appendix; 2011ApJ...737..103S (SF11) recalibration 
of the Schlegel, Finkbeiner & Davis 1998, Appendix B; 1998ApJ...500..525S (SFD98) infrared-based dust map. 
The map is based on dust emission from COBE/DIRBE and IRAS/ISSA; 
the recalibration assumes a Fitzpatrick (1999PASP..111...63F) reddening law with R_v = 3.1 and different source spectrum than SFD98.

NOTE: This information is indicative only. With the exception of the
      redshift they are unreferenced and highly inhomogeneous as to
      their origin. The Radial Velocity (when available) is computed
      from the listed redshift. The remaining values are designed to

      general properties of the object in question. They are not
      averages nor are they standardized in any way.
