Description
One of the important parts of the MPD experiment is the electromagnetic calorimeter ECal, which consists of 50 half-sectors, each containing 768 cells (towers) of different types and spatial orientations [1]. To test the calibration procedure on cosmic ray muons, the half-sector position was changed by rotating it around the central axis, which corresponded to its positions in the final calorimeter assembly. In this report, the effect of the half-sector rotation on calibration coefficients is presented for both experimental and simulation data. The experimental data can also serve as a good test of the angular distribution obtained within the framework of various cosmic ray generators [2, 3].
