We have chosen a sample of 10 coronal loops that were visible on the limb and disk using SXT data. Our analysis was limited to Al1 and AlMg image observations taken when the instrument cycles through different filters during routine operations. The structures of the loop did not appear to change significantly during the cycle. We chose a range of twenty to thirty pixels along each loop and background pixels to correspond with the loop pixels. Temperature analysis was performed in three different ways: (1) standard SXT analysis of the loop pixels with no background subtraction; (2) constant background subtraction for each SXT image; (3) pixel pair background subtraction. Each method produced a temperature estimate for the selected pixels. We are interested specifically in how these results may differ from the EIT and TRACE loop temperature analysis that we have already completed. These results showed that background subtraction did not affect the EIT or TRACE temperatures. Solar physics research at the University of Memphis is supported by NASA grants NAG5-9783 and NAG5-12096.
