Methodology for searching and identifying EAS events in the SIT wide-angle telescope prototype data

Small Imaging Telescope (SIT) - a prototype of a wide-angle telescope with an aperture of about 0.1~m$^2$, equipped with a SiPM matrix, which has a number of advantages over PMTs. This paper presents the data analysis for this telescope, which operates in conjunction with the HiSCORE complex. Events for the years 2019–2022 were analyzed. A total of about 7 million trigger frames were analyzed, among which about 5~million EAS events were detected. The analysis was carried out in several steps: initial tuning of the frames using a synchro pulse, search for events and their cleaning according to the method given in the work.
