AB: The combination of moderate resolution EUV spectroscopy and high resolution narrow band filter images provides the most accurate measure of temperature and density for coronal loops to date. We will demonstrate our technique for combining the data sets from the Coronal Diagnostic Spectrometer on SoHO and the Transition Region and Coronal Explorer. Background subtracted spectral intensities are used to determine the temperature of coronal loops and the TRACE images help determine the loop cross-section, temporal variability, and filling factor. The resulting temperature profiles for multiple positions along a loop leg are determined using the EM LOCI method, and a technique for determining whether a single temperature can characterize the plasma is also presented. We compare the results of our study to current models.
