PUNCH halo CME rendered frames and rotoscoping module

This is a rendered set of frames containing the first halo CME viewed by the PUNCH mission (https://punch.space.swri.edu), 31-May-2025, with preliminary one-off processing before the (superior) official data pipeline was developed in 2025-2026. The data have preliminary flat fielding, preliminary co-alignment, preliminary F-corona subtraction, and an ad-hoc starfield suppression algorithm applied.  They are rendered with a display gamma of 0.55 when displayed on an sRGB (gamma=2.2) device.  Color uses the PUNCH official color table.  

Accompanying the frames is a Python module, rotoscope.py, and a sample notebook, rotoscope.ipynb, that may be used to extract individual points from the data.  The module and notebook were coded using Claude Code and iterative prompting.  The python module and notebook are distributed under the same license as the overall record.  (CCA4.0-intl)

These data and this software were produced by the authors under funding from the PUNCH project.  PUNCH is a heliophysics mission to study the corona, solar wind, and space weather as an integrated system, and is part of NASA’s Explorers program (Contract 80GSFC14C0014).
