The coronal loop data used for this analysis were taken on 2003 January 17 at 14:24:45 UT by the Coronal Diagnostic Spectrometer (CDS) aboard the Solar and Heliospheric Observatory. We use the Chianti atomic physics data base and the hybrid coronal abundances to determine temperatures and densities for positions along several loops. The traditional method used to create our differential emission measure (DEM) curves has been forward folding, but we are now using both emission measure loci plots and DEM automatic inversion to support and confirm the original conclusions. In this poster, we will look specifically at the emission measure loci analysis of three loops visible in the CDS data set. We find different results for each of these loops. One of the loops seems to be composed of isothermal plasma with Log T = 5.8 MK. The temperature does not appear to change with position, from the footpoint to the loop leg. Unfortunately, the loop top is outside the CDS field of view. Each pixel examined in the second loop seems to require a multithermal DEM distribution. For the third loop, the temperature increases and the density appears to decrease with loop height, reminiscent of traditional hydrostatic loop models. Solar physics research at the University of Memphis is supported by NSF ATM-0402729 and NASA NNG05GE68G.
