FOREGROUND GALACTIC EXTINCTION for NGC 1917 (Back to INDEX)|
Galactic Extinction from the Schlafly & Finkbeiner 2011, Appendix; 2011ApJ...737..103S (SF11) recalibration
For completeness, we include the original SFD98 values: WARNING: This position is 51.378 arc minutes from the center of the LMC. The value of E(B-V) is not derived from the IRAS/COBE extinction maps.
Galactic Extinction based on H I Column Densities and Galaxy Counts
(Burstein & Heiles; 1982AJ.....87.1165B) assuming Rv = 3.1:
AB = 0.330 mag
See Notes on Galactic Extinction for important caveats.
