Class CteqPDF

java.lang.Object
  mmc.PhysicsModel
      gen.CteqPDF

All Implemented Interfaces:

FunctionInt, FunctionInt2, FunctionOfx

public class CteqPDF
extends PhysicsModel

Parton distribution functions necessary for neutrino interaction cross sections are calculated here. cteq library is called if the parameterization table ".cteqPDF_raw.data" is not found.

interpolate

public void interpolate()

Creates or reads the ".cteqPDF_raw.data" table.

functionInt

public double functionInt(double x,
                          double q)

2d parametrization - interface to Interpolate

Specified by:

functionInt in interface FunctionInt2

Overrides:
