Solar Stereoscopy and Tomography - Markus J. Aschwanden - 2011

I refer to Aschwanden 2011:
http://solarphysics.livingreviews.org/Articles/lrsp-2011-5/

This is an extremely interesting review paper, 96 pages (19 pages of references) with stunning color graphics. I reproduce 3 figures below, to get your attention !

Dr. Aschwanden is with the Lockheed Martin Solar and Astrophysics Laboratory in Palo Alto California.
