Variations in solar wind fractionation as seen by ACE/SWICS over a solar cycle and the implications for Genesis Mission results
P. Pilleri, D. B. Reisenfeld, T. H. Zurbuchen +5
We use ACE/SWICS elemental composition data to compare the variations in solar wind fractionation as measured by SWICS during the last solar maximum (1999-2001), the solar minimum…
SWAP Observations of the Long-Term, Large-Scale Evolution of the EUV Solar Corona
Daniel B. Seaton, Anik De Groof, Paul Shearer +2
The Sun Watcher with Active Pixels and Image Processing (SWAP) EUV solar telescope on board the Project for On-Board Autonomy 2 (PROBA2) spacecraft has been regularly observing the…
Correcting Camera Shake by Incremental Sparse Approximation
Paul Shearer, Anna C. Gilbert, Alfred O. Hero
The problem of deblurring an image when the blur kernel is unknown remains challenging after decades of work. Recently there has been rapid progress on correcting irregular blur pa…
A generalization of variable elimination for separable inverse problems beyond least squares
Paul Shearer, Anna C. Gilbert
In linear inverse problems, we have data derived from a noisy linear transformation of some unknown parameters, and we wish to estimate these unknowns from the data. Separable inve…
The First Stray Light Corrected EUV Images of Solar Coronal Holes
Paul Shearer, Richard A. Frazin, Alfred O. Hero +1
Coronal holes are the source regions of the fast solar wind, which fills most of the solar system volume near the cycle minimum. Removing stray light from extreme ultraviolet (EUV)…
