%EXP_MOORE1997 Figures from Moore et al. (1997)
%
%   Usage:
%     [dataOut] = exp_moore1997(flags)
%
%   The following flags can be specified:
%     'fig2'    Reproduce Fig. 2 of moore1997.
%
%     'fig3'    Reproduce Fig. 3 of moore1997.
%
%     'fig5'    Reproduce Fig. 5 of moore1997.
%
%     'fig6'    Reproduce Fig. 6 of moore1997.
%
%     'fig7'    Reproduce Fig. 7 of moore1997.
%
%   Examples:
%   ---------
%
%   To display Fig. 2 from Moore et al. (1997) use :
%
%     exp_moore1997('fig2');
%
%   To display Fig. 5 from Moore et al. (1997) use :
%
%     exp_moore1997('fig5');
