Multispectral analysis of solar EUV images: linking temperature to morphology
Thierry Dudok de Wit, F. Auchère · Astronomy and Astrophysics · 2007
Context.Solar images taken simultaneously at different wavelengths in the EUV are widely used for understanding structures such as flares, coronal holes, loops, etc. The line-of-sight integration and the finite spectral resolution of EUV telescopes, however, hinders interpretation of these individual images in terms of temperature bands. Traditional approaches involve simple visualisation or explicit modelling. We take a more empirical approach, using statistical methods.
