AI model for estimation of HB track states was trained through data samples with magnetic field scale factor as 1. Correspondingly, the predicted momentum magnitude needs to be scaled by the magnetic filed scale factor when the model is applied into reconstruction for data with other scale factor of magnetic field.
As Raffaella's test, it should be the reason, that cause KPP test failed in PR#1491
