%CBCS	Variable	Description	Remarks
LINE 1	RBCON	Reference boron concentration in ppm from which the interpolation is done	Dummy if %XTAB card present
LINE 2	CISGTR(g)	Macroscopic Cross Section changes due to changes of boron concentration in ppm	Repeat LINE 2 NG times. And again repeat this input segment NMAT times. This line is not necessary if %XTAB card present
	CSIGA(g)
	CNUF(g)
	CSIGF(g)
	CSIGS(g,1:NG)
LINE 3	POPT	Print option if users want to print this card	Optional
