lbsr.srls:	Creating a parameter file, .dat, to run the prunning 
		program eprbs.srls.

eprbs.srls:	Generating a prunned basis set, .ind, which contains 
		the important basis vectors and make the fitting 
		program nlsl.srls run much faster. 

nlsl.srls:	Fitting multi-frequency ESR spectra using the SRLS
		model.


The model parameters related to SRLS model are:

r0xx r0yy r0zz:	Log_10 of rotation diffusion tensor (s^-1) of cage;
a_20, a_22:	coefficients for orienting potential of cage;
beg:		cage tilt angle between cage axis and internal
		orienting potential axis.


The description of other model parameters can be found in main page.
