General Requirements for a simulation of the IFR
Muons/Pions separated using:

- veto on E_cal;
- number of LambdaInt_meas (estimated from the last layer hit);              
- LambdaInt_meas - LambdaInt_exp in the mu hypothesys;                         
- chi2/ndof of the IFR-hit strips from a simple fit of the layer 
  clusters;     
- chi2/ndof of the IFR-hit (strips) respect to the track estrapolation;
- track continuity
- sigma of the average multiplicity of hit strips per layer;

These information are the input of a NN (or a cut based selection).

It is needed a reliable hadron interaction in the BABAR detector & IFR 
(1 LambdaInt before the IFR).

PravdaMC

IFR not simulated, only the overall PID-output is given 
- from Pid-Tables obtained from muon-hadron control samples (?);
- in different environment/geometry these tables should be recomputed.

Possible development: generate all relevant variables parametrically 
and use these as input to a muon selector;
- but the parameterizations should be extracted from ad-hoc 
studies/assumptions and using a (almost)full-simulation.

------------------------------------------------------------------------
Optimization of the detector design:
- z-resolution, scintillator width;
- effect of the machine background ?;

It is enough a parametric simulation (like Pravda)? some of these studies
kind could be done within the present BaBar environment 
(change the geometry of the strips, increase the strip occupancy by 
layer, etc...).
