The Cherenkov Telescope Array (CTA) will be the next-generation observatoryin the field of very-high-energy (20 GeV to 300 TeV) gamma-ray astroparticlephysics. The traditional approach to data analysis in this field is to applyquality cuts, optimized using Monte Carlo simulations, on the data acquired tomaximize sensitivity. Subsequent steps of the analysis typically use thesurviving events to calculate one set of instrument response functions (IRFs)to physically interpret the results. However, an alternative approach is theuse of event types, as implemented in experiments such as the Fermi-LAT. Thisapproach divides events into sub-samples based on their reconstruction quality,and a set of IRFs is calculated for each sub-sample. The sub-samples are thencombined in a joint analysis, treating them as independent observations. Inprevious works we demonstrated that event types, classified using MachineLearning methods according to their expected angular reconstruction quality,have the potential to significantly improve the CTA angular and energyresolution of a point-like source analysis. Now, we validated the production ofevent-type wise full-enclosure IRFs, ready to be used with science tools (suchas Gammapy and ctools). We will report on the impact of using such anevent-type classification on CTA high-level performance, compared to thetraditional procedure.
