  1. LWS Proposal • 3D Reconstruction of White Light Coronagraph Images from Multiple Viewpoints • PI John Cook, Co-I’s Jeffrey Newmark, Paulett Liewer, Collaborators Paul Reiser, Amos Yahil • Example of the 3D electron density reconstruction of a constant density half shell observed from three viewpoints in the ecliptic plane, using the PIXON reconstruction algorithm employed in our proposal • Top: Schematic of hemispherical shell (model CME) ejected from Sun, viewed by SECCHI coronagraphs on Ahead (A) and Behind (B) twin STEREO spacecraft, and by LASCO on SOHO • Middle: Visualization of the input model half shell (top row) and the reconstructed object (bottom row), from x, y, z, and (-45o, +45o) directions • Bottom: Synthetic white light CCD pictures, in radial and tangential polarizations, from the three viewpoints of B, Earth (LASCO on SOHO), and A coronagraphs. Original input CCD pictures (top row), and CCD pictures resulting from the 3D reconstruction (bottom row)
