| Abstract: |
The prototype of the Large-Sized Telescope (LST) of the Cherenkov Telescope Array (CTA) is presently going through its commissioning phase. A total of four LSTs, among others, will operate together at Observatorio del Roque de Los Muchachos, which will host the CTA North site.
A computing center endowed with 1760 cores and several petabytes disk space is installed onsite. It is used to acquire, process, and analyze the data produced, at a rate of 3 TB/hour during operation. The LST On-site Analysis LSTOSA is a set of scripts written in Python which connects the different steps of lstchain, the analysis pipeline developed for the LST. It processes the data in a semiautomatic way producing high-level data and quality plots including detailed provenance logs. Data are analyzed before the next observation night to help in the commissioning procedure and debugging. |
