 The base class function `MeasurementBase::Reconfigure()` specifies `isSignal(FitEvent *)` which is what we will implement in our class. Since we plan on re-using the signal definition for multiple distributions, we should include it in the `src/T2K/T2K_SignalDef.cxx` implementation, as mentioned [#point_signal earlier].

 We prefer a clear unambiguous naming scheme, so let's name the namespace function `isCC1pip_T2K_H2O`. The function will need to take the `FitEvent` object along with the `EnuMin` and `EnuMax` defined in the experiment signal definition.
 
-In the signal definition we can use already declared functions of the namespace `SignalDef`. These live in `src/Utils/SignalDef.cxx`. We can see a `SignalDef::isCC1pi(FitEvent *, int nuPDG, int piPDG, double EnuMin, double EnuMax)`. This helper function searches for:
