Vibute, IUCAA, Pune et al (TBD) Abstract Type : Invited Abstract Category : Instrumentation and Techniques Abstract : The CZT Imager aboard the ASTROSAT mission will employ Coded Mask Imaging technique for locating sources at high energy X-rays. For image reconstruction from this data we have developed a number of techniques based on cross-correlation, model-fitting and Bayesian inference methods. We apply a combination of these techniques to ground calibration data of CZTI and demonstrate an angular resolution of better than 8 arcmin. A comparative study of the error budget in flux and location obtained in these techniques is presented. |
