lstchain: An analysis pipeline for LST-1, the first prototype Large-Sized Telescope of CTA

The future Cherenkov Telescope Array (CTA) will have telescopes of different sizes, being the Large Sized Telescopes (LSTs) the largest ones. Located on the island of La Palma, the LST-1, the prototype of the first LST, started taking astronomical data in November 2019, detecting the first gamma-ray sources right afterwards. The analysis pipeline, that processes data from raw inputs until high level products is called lstchain and is heavily based in the CTA prototype pipeline framework ctapipe. In this presentation I'll show the pipeline that performs signal integration, image cleaning, image parameter calculation, and machine learning methods for true parameter reconstruction.
