• The intended beamspot is specified in workflow 11624.0 GEN-SIM
• Changes are present only in the 2021 realistic scenario (workflow 11624.0)
• Changes are seen in many comparison test histograms as the GEN-SIM is changed

@prebello @zhenhu any objection? Otherwise could you please sign it? DQM differences are present only for the 2021 workflow, as expected
