Bright points (BPs) are small bi-polar regions on the Sun with temperatures that range from 1 MK to 2.5 MK. We are in the initial stages of a statistical study of BP properties including the relationship between the BP differential emission measure (calculated from image data) and size. In this poster, we present preliminary results on the ability to calculate the BP differential emission measure using AIA data. We will answer the question: Can observations from AIA alone constrain the differential emission measure of BPs? First, we define a hypothetical differential emission measure and calculate the expected AIA and XRT intensities. We then attempt to reconstruct the differential emission measure from a subset of the intensities. We determine the minimum intensities required for differential emission measure calculation. We then present the differential emission measure of an observed BP determined from EIS intensities and demonstrate the ability of the AIA and XRT intensities to calculate it.
