Correlations between MIR, FIR, H$\alpha$, and FUV Luminosities for SWIRE galaxies

The figure shows the correlation between observed H-alpha + 24 micro (y-axis, left-hand panel) and H-alpha + 8 micro (y-axis, right-hand panel) luminosities with the extinction-corrected H-alpha luminosities (x-axis) for star-forming galaxies selected from the Spitzer-SWIRE fields.

Filled circles: Normal galaxies
Open circles: Dwarf galaxies
Lines: Best nonlinear (solid) and linear (dotted) fit
