Interpreting SECCHI White Light Images: FOV Sensitivity

For 3D viewing (goggles, etc.) and quantitative stereoscopy, mu. st see same features in both views Depends heavily on viewing geometDepends heavily on viewing geometryry: stereo angle and overlap of Fields-Of-View (FOV) and sensitivity of FOV For interpretation of small and large angle stereo views & tomography Great

Hinode, CORONAS, and the Solar Dynamics Observatory (SDO) during the era of 2000-2018. The new solar space missions are characterized by unprecedented high-resolution imaging, time resolution, spectral capabilities, stereoscopy and tomography, which reveal the intricate dynamics of magneto-hydrodynamic processes in the solar corona down to scales

mapping solar coronal magnetic fields including transverse component directions and line-of-sight component intensi-ties. Solar tomography, or stereoscopy based on EUV ob-servations, can supply 3-D information for some magnetic field lines in bright EUV loops. In a previous paper ( Liu and Lin, 2008) the locations of the IR emission sources

Finally we mention exten-sions to plain stereoscopy such as a third view, a tomography-like approach and how magnetic field information can be used to improve the reconstruction. 1 Introduction

dedicated 3-dimensional (3D) information of solar-terrestrial phenomena. Some 3D modeling has been accomplished before, of course, e.g., by means of solar-rotation tomography, combined imaging and Doppler-spectroscopy, or multiple in-situ spacecraft observations of the solar wind (such as with CLUSTER), but

This provided a unique opportunity to establish the absolute pointing of the COR1-B COR1 observes in a white-light waveband 22.5 nm wide centred at the Hα line at 656 nm.

Also, the discussion of the solar atmosphere and activity is limited to those topics of direct relevance to the magnetic field. After giving a brief overview about the solar magnetic field in general

We show that tomog-raphy and stereoscopy are complementary to study polar plumes. We also show that this systematic 2D identification and the proposed methods of 3D reconstruction are well
