CASS/UCSD SWG SMEI observations and comparison with STEREO CASS/UCSD SECCHI OCT 2008 We have now devised a wealth of “tools” to understand and analyze the SMEI image data, and to ascertain how well the SMEI 3D reconstructions work. Provided the HI-2 instruments have the stability to provide brightness above a long- term base (we think they do), we now have the tools required to view common structures and to reconstruct the regions in common between the HI-2 and SMEI. Summary and where are we going:
