However, it is seriously hampered by the restrictive assumption that the corona is time-invariant which introduces significant errors in the reconstruction. We first explore several methods to mitigate the temporal variation of the corona by decoupling the \"fast-varying\" inner corona from the \"slow-moving\" outer corona using multiple masking (either by juxtaposition o","authors_text":"Christelle Peillon, Didier Vibert, Julien Wojak, Philippe Lamy, Richard A.
