The fact that a galaxy is barred may have an effect on the source of the far-infrared (FIR) radiation observed. Yet, to date, no one has addressed the effects that that might have on interpreting the global FIR signal. We hope to add to the existing data on FIR radiation in galactic bulges by comparing a barred galaxy, M83, to an unbarred galaxy, M74.

We use optical, Ha and UV images that are blurred to the same resolution as the IRAS HIRES images. Looking at the blurred UV images, bright "globs" were chosen and apertures were fit to them. The “globs” were then located on the optical, Hα and FIR images and fluxes were determined for each aperture used.
