Comparison of image parameters between the Data and MC simulations (for zenith distance below 30°). Top four rows of panels show intensity, length, width, and individual telescope “gammaness” (from top to bottom) for LST-1 (left), MAGIC-I (middle) and MAGIC-II (right). The bottom row shows stereoscopic parameters: height of the shower maximum (left) and averaged “gammaness” (right). In all the panels: the thick blue line shows the data, while the thick magenta line shows the sum of all MC components. Thin lines show the individual components: protons (orange), helium (with an additional correction for heavier elements (green), and all-electrons (red).
