The Quasi-Radial Field-line Tracing (QRaFT): an Adaptive Segmentation of the Open-Flux Solar Corona
Vadim M. Uritsky, Christopher E. Rura, Cooper Downs +3
Optical observations of solar corona provide key information on its magnetic geometry. The large-scale open field of the corona plays an important role in shaping the ambient solar…

Improved Tomographic Reconstruction of 3D Global Coronal Density from STEREO/COR1 Observations
Tongjiang Wang, C. Nick Arge, Shaela I. Jones
Tomography is a powerful technique for recovering the three-dimensional (3D) density structure of the global solar corona. In this work, we present an improved tomography method by…
