Abstract

We develop a new procedure to improve the angular resolution of coded-mask telescopes by the Direct Demodulation Method (DDM). DDM has been applied to both real and simulated data of INTEGRAL/IBIS. The angular resolution of IBIS/ISGRI has been improved from about 13' to 2'.

直接解调提高编码掩模望远镜的角分辨率

本文提出了一种利用直接解调法(DDM)提高编码掩模望远镜角分辨率的新方法。DDM已应用于INTEGRAL/IBIS的真实数据和模拟数据。IBIS/ISGRI的角分辨率从13'左右提高到2'左右。
