    FOREGROUND GALACTIC EXTINCTION for NGC 1831 (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.
    WARNING: This position is 306.867 arc minutes from the center of the LMC. The value of E(B-V) is not derived from the IRAS/COBE extinction maps.
    See SFD98.
