The Wide Field Imager (WFI) Instruments for the Polarimeter to Unify the Corona and Helliosphere (PUNCH)
Glenn T. Laurent, Craig E. DeForest, Matt N. Beasley +14
We describe the design, hardware integration, and calibration performance of the Wide-Field Imager (WFI) instruments for the Polarimeter to Unify the Corona and Heliosphere (PUNCH)…
Tracking the Activity of the Interstellar Object 3I/ATLAS through its Perihelion
T. Marshall Eubanks, Craig E. DeForest, Kevin J. Walsh +10
In order to facilitate interplanetary spacecraft observationsof 3I/ATLAS, we have monitored and predicted the optical properties of its coma using both ground and space-based obser…
The Stationary Point: A New Method for Solar Wind Speed Measurements from a Moving Vantage Point
Samuel J. Van Kooten, Craig E. Deforest, Guillermo Stenborg +1
The WISPR imager on Parker Solar Probe provides a unique view the young solar wind, flying through solar wind structures at high speed. It is of interest to use WISPR image sequenc…
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…
