int getNumCrossSectionDataPoints

(

const char *

filename

)

Counts the number of lines in an cross-section input file.

Parameters

filename

the file of interest

Returns

the number of lines in the file

const char* getXSLibDirectory

(

)

Returns the directory for the cross-section library directory.

Returns

a character array with the cross-section library directory

int parseCrossSections	(	const char *	file,
		float *	energies,
		float *	xs_values
	)

Parses an input file of cross-section data.

Loads the energy values (as eV) and the cross-section values (barns) into two float arrays. It takes in the energies in MeV since that is the most typical unit for ENDF nuclear data, but converts the values into eV during parsing.

Parameters

file	the filename for the data
energies	a pointer to a float array for the energies (MeV)
xs_values	a pointer to a float array fo the xs values (barns)

Returns

the number of data points

int restoreXSLibrary

(

)

Restores the cross-section library to its original, installed state.

This function copies the original cross-section data files installed with PINSPEC from the pinspec/xs-lib/BackupXS folder into the main cross-section library directory pinspec/xs-lib. This function is primarily when a user is using PINSPEC's SLBW module to create artifical cross-sections from Reich-Moore date. This function is called anytime the python pinspec module is imported.

Returns

returns an int representing whether or not the copy was successful

void setXSLibDirectory

(

const char *

xs_directory

)

Sets the directory for the cross-section library.

Parameters

xs_directory

character array for the cross-section library directory
