%DATA_SABIN2005 Data retrieved from Figures 8-10 of Sabin et al. (2005)
%   Usage: data = data_sabin2005
%
%   DATA_SABIN2005 returns percentage of quasi-veridical responses
%   (audible and within 45 deg of the regression line) as a function of
%   sensation level averaged across all listeners.
%
%   The data struct comprises the following fields:
%
%     'gain'   gain of regression line. Field f*
%              for frontal targets, field r for rear targets. Field
%              m for across-listener means, field sd for standard
%              deviation across listeners
%     'pqv'    percent quasi-veridical responses (within +-45 deg 
%              relative to regression line. Fields as for gain.
%     'var'    standard deviation of quasi-veridical responses from 
%              regression line . Fields as for gain.
%     'SL'     sensation level in dB (re audibility threshold)
