Advanced Processing of Gamma Events at SLAC: Filtered Background and Event Analysis

This dataset provides processed gamma events from SLAC, focusing on a comprehensive set of filters applied to enhance data quality. Key criteria include high filter status, track count, raw energy thresholds, energy probability measures, and spatial distribution functionalities. Available files document the processing of 500M background events and 2M gamma events, facilitating in-depth analysis of effective area vs. background rates, alongside energy probability distributions. This resource supports researchers in astrophysics and high-energy physics, interested in gamma-ray data.
