kHadronTensorGridFlag_t

enum anonymous_namespace{TabulatedLabFrameHadronTensor.cxx}::kHadronTensorGridFlag_t

Enumerated type that represents the format used to read in grid points from the hadron tensor data file

Enumerator
kStartAndStep	A starting value and a step size are used to define a regular grid.
kExplicitValues	An explicit table of grid points is used to define an irregular grid.
kHadronTensorGridFlag_COUNT	Dummy value used for error checking.

real_sqrt()

double anonymous_namespace{TabulatedLabFrameHadronTensor.cxx}::real_sqrt

(

double

x

)

Definition of sqrt() that returns zero if the argument is negative. Used to prevent spurious NaNs due to numerical roundoff.
