Solar Spectrum Atomic Database Update Comparisons
Abstract
Computations of the solar spectrum from 1 Å to 100 microns are obtained through the Solar Radiation Physical Modeling (SRPM) system. However, this presentation examines in detail only the range 1 to 2020 Å. Comparisons are made between the spectra generated by SRPM including CHIANTI-5 atomic data, the CHIANTI-6 atomic data with no change to the elemental ionization formulation, and the CHIANTI-6 atomic data with the new ionization formula used in this version. The extreme ultraviolet (EUV) part of the spectrum is compared with observations made by the Solar Dynamics Observatory's EUV Variability Experiment (SDO/EVE). In addition, the SDO Atmospheric Imaging Assembly (AIA) data are analyzed for the generation of solar feature masks. These include photospheric, chromospheric, and coronal layers. Examples are shown of the routine daily masks and spectra generated.
