Function Documentation

void printBField	(	std::string	inFile,
		std::string	treeName,
		std::string	outFile,
		float	rmin,
		float	rmax,
		float	zmin,
		float	zmax,
		int	nBins
	)

to print out the FCC field map please use

printBField("FCChhBField.root","bField","printBField_FCC.root",-20.,20.,-30.,30.,400.)

ro print out the ATLAS BField map pleas use

printBField("ATLASBField.root","bField","printBField_ATLAS.root",-10.,10.,-15.,15.,200.)

Parameters

inFile	The root input file containing the magnetic field values and positions either in cylinder (Branch names: 'r','z','Br','Bz') or cartesian coordinates (Branch names: 'x','y','z','Bx','By','Bz')
the	name of the tree containing the branches
rMin	The minimum value of the position in either r (for cylinder coordinates) or x/y (for cartesian coordinates) to be printed in [m]
rMin	The minimum value of the position in either r (for cylinder coordinates) or x/y (for cartesian coordinates) to be printed in [m]
rMin	The maximum value of the position in either r (for cylinder coordinates) or x/y (for cartesian coordinates) to be printed in [m]
rMin	The minimum value of the position in z in [m]
rMin	The maximum value of the position in z in [m]
nBins	Number of bins which should be used for the histogram (on all axes)

Note

This script just writes out the values which are read in from the given input file. It does no interpolation inbetween the values. This means, in case the binning is chosen too high, empty bins will appear.
