Astrosat First Light: CZT Imager Looks at Crab Nebula
Astrosat , India's first Multi-wavelength Space Observatory was successfully launched by ISRO's workhorse launch vehicle PSLV into a 650km orbit on September 28, 2015. Then began the process of putting each of the payloads into operation. Charge Particle Monitor (CPM) was the first payload to go operational followed by the Cadmium Zinc Telluride Imager (CZTI), the hard X-ray detector on board Astrosat. CZTI was made fully operational on October 5, 2015. Then, October 6, Astrosat was oriented towards Crab Nebula, remnant of the Supernova detected by Chinese astronomers in the year 1054. The Crab Nebula, which also includes the Crab Pulsar, is the brightest hard X-ray source in the sky, and is very often used to calibrate hard X-ray detectors.

CZTI Detectors
CZTI consists of four quadrants of 16 pixelated detectors each, achieving a total geometric area of 976 cm2. It is sensitive to X-rays above 10 keV energy. For every photon it detects, CZTI sends an event report consisting of position (pixel number, each pixel – 2.5mm X 2.5mm), time of detection (correct to 20 micro-seconds) and energy of the incident photon.

some how can't post the whole thing.....
