    FOREGROUND GALACTIC EXTINCTION for NGC 3447 (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 Rv = 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
          orient the user with a quick-look, overall assessment of the
          general properties of the object in question. They are not
