Analysis of a coronal loop on the limb

Abstract

The ability to accurately measure the temperature and density of the solar atmosphere is essential to understanding the physical nature of Coronal loops. After data has been corrected to account for cosmic ray incidents on the CCD and instrumental effects, there are additional sources of error that must also be addressed. We applied a correction to the intensities for spectral lines to account for line of sight effects. Having performed these procedures, the corrected intensities from the Coronal Diagnostic Spectrometer are then used to produce differential emission measure curves with much improved error estimates
