function tau  = data_neely1988(F,L,varargin)
%DATA_NEELY1988 ABR wave V data as functon of level and sweeping rate
%   Usage: tau = data_neely1988(flag)
%
%   Input parameters:
%     F    : Centre frequencies of stimulus
%     L    : Levels at centre frequencies
%
%   Output parameters:
%     tau  :  Wave V latency
%
%   DATA_NEELY1988(F,L) returns data points based on equation 1 from
%   Neely et al. (1988) where F is the centre frequencies and L are
%   the associated levels. 
%
%   The flag may be one of:
%
%     'no_plot'  Don't plot, only return data. This is the default.
%
%     'plot'    Plot the data.
%
%   Examples:
%   ---------
%
%   Figure 2 in Neely et al. (1988) can be reproduced using:
%
%     F=[250 500 1000 2000 5000 8000];
%     tau=data_neely1988(F,[40 60 80 100]);
%     loglog(F,tau','k-');
%     xlabel('CF');
%     ylabel('Latency [ms]')
