Description

The Cherenkov Telescope Array (CTA) is the next generation TeV gamma-ray observatory and the first prototype of the Large Sized Telescope (LST-1) was built in La Palma, Spain and is in its commissioning phase. Since one of the current generation TeV telescopes, MAGIC, is operating in the same site, it is possible to observe the same gamma-ray events with both instruments and perform joint stereoscopic analysis with both higher collection area and stronger background rejection. Therefore we routinely perform joint observations. We report the newly developed analysis pipeline for analysis of such joint data and its performance based on both the Monte Carlo simulations and data collected from the Crab Nebula. We find the joint observations allows us to detect 30% weaker sources compared to MAGIC-alone analysis and 40% compared to LST-1-alone analysis.
