Large-Scale Structure of the Atmosphere of the Quiet Sun, Coronal Holes, and Plages as Deduced by Tomography Study
Abstract
We present here the results of emission tomography studies, based on a new differential deconvolution method (DDM) of Laplace transform inversion, which we use for reconstruction of the coronal emission measure distributions in the quiet Sun, coronal holes and plage areas. Two methods are explored. The first method is based on the deconvolution of radioemission brightness spectra in a wide wavelength range (1 mm-100 cm) for temperature profile reconstructions from the corona to the deeper chromosphere. The second method uses radio brightness measurements in the cm-dm range to give a coronal column emission measure (EM).
