TL;DR: In this article, the spectral energy distributions (SEDs) of the four emission components are identified by constructing spectral energy distribution at position along the Galactic plane using the wide frequency coverage of 28.4−857 GHz in combination with low-frequency radio data at 23−94 GHz, along with far-infrared (FIR) data from COBE-DIRBE and IRAS.
