Using EUV image data from the Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory, we have done multi-thermal analysis along the entire length of a collection of coronal loops. The six coronal filters of AIA peak at different temperatures to produce data that span the entire range of temperatures found in these loops. We have selected cooler loops for this analysis that were chosen from images taken with the 171-A filter, which has a peak response temperature around 0.63 MK. The object of this investigation is to determine if the plasma is isothermal or multi-thermal either (a) along the line of sight or (b) along the length of the loop. We have used both an automatic and a manual method to determine the Differential Emission Measure (DEM) distribution at the loop apex and the foopoints. We find that the temperature distribution is narrow, but not consistent with isothermal plasma. In addition, the DEM-weighted temperature changes much less along the loop length than predicted by standard RTV models.
