//

//  Hello PID Fans:

//

//  This is the base class for a simple set of objects that

//  are used to evaluate various detector technology choices for the EIC.

//

//  The idea is simple.  Regardless of PID detector technology choice

//  one must be able to answer some simple questions.  This virtual base class

//  organizes the method of asking and answering these simple questions to

//  allow for efficient and apples-to-apples comparisons.

//

//  The base class requires that any derived class procide responses to several queries:

//   -- valid   (double eta, double p                      );

//   -- numSigma(double eta, double p,        PID::type PID);

//   -- maxP    (double eta, double numSigma, PID::type PID);

//   -- minP    (double eta, double numSigma, PID::type PID);

//   -- name    ();

//

//  Here PID::type is an enumerated constant set allowing one to choose pi-vs-k or k-vs-p etc...

//

//  The detector types that inherit from PID will clearly have parameters that define their

//  performance and these are expected to be arguments of the constructor of those derived classes.

//  For example:

//     PID* tof = new tofBarrel(radius, etaLow, etaHigh, sigmaT);

//

//
