Abstract
The Coronal Diagnostic Experiment (CODEX), a solar coronagraph developed by NASA-Goddard Space Flight Center in collaboration with the Korea Astronomy and Space Science Institute (KASI) and the Italian National Institute for Astrophysics (INAF), was successfully operational on-board the International Space Station (ISS) from December 2024 to September 2025. During its nine months of operation, CODEX executed four dedicated radiometric campaigns. These campaigns were crucial for performing in-flight radiometric calibrations, a fundamental step required to convert the measured raw data (counts) into meaningful physical units. The calibration was achieved by repeatedly targeting a select number of bright stars within the instrument’s pointing range, for which well-characterized spectra were available. This presentation describes and analyzes the dataset, methodology, and results of this essential radiometric calibration effort

INAF - Osservatorio Astrofisico di Torino (Italy)
Employee of the National Institute for Astrophysics (INAF) in Turin, Italy, his work focuses on the design, development, and verification/validation of ground-based and space instrumentation. This instrumentation is primarily dedicated to the study of the Sun, the solar corona, and the dynamics of its interaction with the Earth. He is an expert in polarimetry and have actively participated in several major observational campaigns. These experiences include scientific expeditions in Antarctica and fieldwork for solar eclipse observations.
