| Abstract: |
We derive new calibrations for far-ultraviolet (FUV) attenuation as
derived from the total infrared (TIR) to FUV luminosity ratio (IRX)
and the FUV-NUV color in an empirical way. We find that the
IRX-corrected FUV luminosities are tightly and linearly correlated
with the dust corrected Hα luminosities (as derived from the
Balmer decrement), with a rms scatter of ± 0.09 dex. Therefore
combinations of observed FUV luminosities and TIR luminosities are
good star formation rate tracers. In contrast, the correlation
between FUV-NUV color corrected FUV luminosities and
Balmer-corrected Hα luminosities shows much larger (∼
2.5 times) rms scatter and non-linearity. |
