Jitter sensing and reconstruction from temporal series of solar images: Applications to TuMag

Astronomy & Astrophysics
Context. Images recorded with the Tunable Magnetograph (TuMag) instrument on board the SUNRISE III balloon observatory are affected by temporal contrast fluctuations. These variations are related to high-frequency vibrations (jitter) of the platform that
