Abstract Simulated events are key ingredients in almost all high-energy physics analyses. However, imperfections the simulation can lead to sizeable differences between observed data and simulated events. The effects of such mismodelling on relevant observables must be corrected either effectively via scale factors, with weights or by modifying distributions their correlations. We introduce a correction method that transforms one multidimensional distribution (simulation) into another (data) using simple architecture based single normalising flow boolean condition. demonstrate effectiveness physics-inspired toy dataset non-trivial several
