Spectral energy distributions of the two star-forming regions: central region single-burst case (left panel), central region continuous case (middle panel), and southern region single-burst model (right panel). The black and blue curves correspond to the input and output SEDs, respectively. The dotted lines are the attenuated input SEDs. The data points are the photometry measurements from GALEX FUV, 2MASS J, H, K bands, MIPS 24  μm, and PACS at 70 μm, 100 μm, and 160  μm. In panels for the central region, the dashed curves are scaled versions of the output SEDs, considering a covering factor of 0.5 for the PDR.
