The PF algorithm discussed in Sect.  4.1 reconstructs physics objects with high efficiencies. However, physics analyses often require tighter quality criteria for certain physics objects in order to further suppress backgrounds that contain other physics objects misidentified as objects of interest. This, of course, comes at the cost of slightly lower efficiencies. Furthermore, certain additional corrections are often applied to improve the resolution of energy measurements of certain particles. This section discusses the additional corrections and quality criteria that have been used to define physics objects used in the presented analyses.
