Coma Off It: Removing Variable Point Spread Functions from Astronomical Images
J. M. Hughes, C. E. DeForest, D. B. Seaton
We describe a rapid and direct method for regularizing, post-facto, the point-spread function (PSF) of a telescope or other imaging instrument, across its entire field of view. Ima…
Direct observations of a complex coronal web driving highly structured slow solar wind
L. P. Chitta, D. B. Seaton, C. Downs +2
The solar wind consists of continuous streams of charged particles that escape into the heliosphere from the Sun, and is split into fast and slow components, with the fast wind eme…
Defining the Middle Corona
Matthew J. West, Daniel B. Seaton, David B. Wexler +31
The middle corona, the region roughly spanning heliocentric altitudes from to , encompasses almost all of the influential physical transitions and processes that…
Square Root Compression and Noise Effects in Digitally Transformed Images
C. E. DeForest, C. Lowder, D. B. Seaton +1
We report on a particular example of noise and data representation interacting to introduce systematic error. Many instruments collect integer digitized values and appy nonlinear c…
Prominence eruption observed in He II 304 Å up to $>6 R_\sun$ by EUI/FSI aboard Solar Orbiter
M. Mierla, A. N. Zhukov, D. Berghmans +24
We report observations of a unique, large prominence eruption that was observed in the He II 304 Å passband of the the Extreme Ultraviolet Imager/Full Sun Imager telescope aboard S…
Direct First PSP Observation of the Interaction of Two Successive Interplanetary Coronal Mass Ejections in November 2020
Teresa Nieves-Chinchilla, Nathalia Alzate, Hebe Cremades +18
We investigate the effects of the evolutionary processes in the internal magnetic structure of two interplanetary coronal mass ejections (ICMEs) detected in situ between 2020 Novem…
Simultaneous High Dynamic Range Algorithm, Testing, and Instrument Simulation
James Paul Mason, Daniel B. Seaton, Andrew R. Jones +4
Within an imaging instrument's field of view, there may be many observational targets of interest. Similarly, within a spectrograph's bandpass, there may be many emission lines of…
