Abstract: We present a method for constructing Differential Emission Measures (DEMs) using data from solar imagers such as EIS and AIA. The method is simple, and very fast (∼ 1 minute per full disk AIA image). We analyze the fidelity of the method, and apply it to a coronal loop observed on April 19, 2011. The method appears to give reasonable results, although reconstructed DEMs can contain regions of moderately negative emission measure (EM). Both EIS and AIA DEM reconstructions suggest that the loop has a narrow temperature distribution centered at 1.2 MK, situated in a diffuse background of broader temperature distribution centered at 3 MK.
