The Cadmium–Zinc–Telluride Imager on AstroSat has proven to be a very effective All-Sky monitor in the hard X-ray regime, detecting over three hundred GRBs and putting highly competitive upper limits on X-ray emissions from gravitational wave sources and fast radio bursts. We present the algorithms used for searching for such transient sources in CZTI data, and for calculating upper limits in case of non-detections. We introduce CIFT: the CZTI Interface for Fast Transients, a framework used to streamline these processes. We present details of 87 new GRBs detected by this framework that were previously not detected in CZTI.

AstroSat 上的镉-锌-碲化物成像仪已被证明是硬 X 射线范围内非常有效的全天监视器，可检测到 300 多个 GRB，并对来自引力波源的 X 射线发射设置了极具竞争力的上限和快速无线电爆发。我们介绍了用于在 CZTI 数据中搜索此类瞬态源以及在未检测到的情况下计算上限的算法。我们介绍了 CIFT：用于快速瞬变的 CZTI 接口，这是一个用于简化这些过程的框架。我们提供了此框架检测到的 87 个新 GRB 的详细信息，这些 GRB 以前在 CZTI 中未检测到。
