The Cadmium Zinc Telluride Imager (CZTI) is a high energy, wide-field imaging instrument on AstroSat. CZTI’s namesake Cadmium Zinc Telluride detectors cover an energy range from 20 keV to $$>200$$ > 200 keV, with 11% energy resolution at 60 keV. The coded aperture mask attains an angular resolution of 17 $$^\prime $$ ′ over a 4.6 $$^\circ $$ ∘ $$\times $$...
