| Abstract: |
SPIRIT spectroheliograph aboard CORONAS-F satellite operated on orbit from Aug 2001
to Dec 2005. The spectroheliograph consisted of two similar channels, for
176–207 Å and 280–330 Å, each channel was built on slitless optical
scheme with grazing incidence diffraction grating. During the CORONAS-F mission
the spectroheliograph registered several dozens of extreme solar flares. We
developed a method of the spectroheliograph data interpretation, which is based
on spectrum modelling. We investigated spectrum of X3.4 flare of 28th Dec 2001
and analyzed spectral line intensities and DEM. Accuracy of
experiment/theory ratio of line intensities is about a factor of 2. Some systematic
discrepancies have been found. |
