Detailed Description

The ExtrapolatorComparisonTest Algorithm runs a number of n test extrapolations from randomly distributed Track Parameters to reference surfcas within.

• a) the Inner Detector if DetFlags.ID_On()
• b) the Calorimeter if DetFlags.Calo_On()
• c) the Muon System if DetFlags.Muon_On()

It uses and compares the output obtaining using the ATLAS Extrapolator and the ACTS Extrapolation
