PICsIT (Pixellated Imaging CaeSium Iodide Telescope) is the high energy detector of the IBIS telescope on-board the INTEGRAL satellite. It consists of 4096 independent detection units,0.7 cm 2 in cross-section, operating in the energy range between 175 keV and 10 MeV. The intrinsically low signal to noise ratio in the gamma-ray astronomy domain implies very long observations, lasting 10 5 -10 6 s. Moreover, the image formation principle on which PICsIT works is that of coded imaging in which…

Analysis of extremely low signal-to-noise ratio data from INTEGRAL/PICsIT
Context. The PICsIT detector onboard the INTEGRAL satellite was designed to provide information about emission in the soft γ-ray band for many bright sources. Due to strong and variable instrumental
Overview of High-Precision Spectral Payload On-Orbit Radiometric Calibration
TLDR
Aiming at the large-caliber spectral load, this paper proposes an on-orbit scale calibration scheme combined with “full aperture part of the optical path calibration” and “all optical path part of of the aperture calibration’.
