The absolute diffuse calibration of the Multiband Imaging Photometer for Spitzer (MIPS) 24 µm channel is investigated by analysis of a sample of H II regions with a wide range of spatial scales near l = 312°. For each region, sky-subtracted, point-source-subtracted, areally integrated MIPS24 fluxes from the MIPSGAL Legacy program are compared with Midcourse Space Experiment (MSX) 21.3 µm fluxes to determine the flux ratio of MIPS24/MSX 21.3 µm. Spectral energy distributions of these regions indicate that the diffuse calibration of MIPS24 is consistent to within 3% (1σ) with the absolutely validated calibration of MSX.
