function data = data_breebaart2001(varargin)
%DATA_BREEBAART2001 Returns data points from the Breebaart et al. (2001b) paper
%   Usage: data = data_breebaart(figure,nfc)
%
%   data_breebaart(figure,nfc) returns data from Breebaart et al. (2001b)
%
%   The flags fo the figure may be one of:
%
%     'fig3'      Returns the N0Spi values for figure 3
% 
%     'fig6'      Returns the NpiS0 values for figure 6
%
%   The nfc (center frequency of noise) may be one of: 
%
%     'nfc125','nfc250','nfc500','nfc1000': figure 3 and figure 6
%
%     'nfc2000','nfc4000':                  figure 3 only
%
%   For the data points one can choose between
%
%     'breebaartmodel'  Returns the data points derived from the model of
%                       Breebaart et al. (2001b). This is the default.
%                       
%     'vandepaar'       Returns the data points Breebaart used in Fig. 1
%                       from van de Paar and Kohlrausch (1999)
%
%   Examples:
%   ---------
% 
%   To get data for the fig. 3 Breebaart et al. (2001b) for the 
%   condition with 125 Hz center frequency use :
%
%     data_breebaart2001('fig3','nfc125');
