Energy and Spatial Resolution of HyCal

This report presents the energy and spatial resolution analysis of HyCal detector system, comparing energy and position resolutions against incident energy and position. It includes information on lead tungstate and lead glass materials, resolution curves, Gaussian fit results, position information, run details, simulation results, and comparison with prototype resolution curves. Key areas discussed include energy clustering histograms, linearity of energy reconstruction, single Gaussian fitting, and simulated X distribution analysis. The findings highlight the importance of studying behavior at cell edges and the need for deep statistic scans.
