%DEMO_BAUMGARTNER2014 Demo for sagittal-plane localization model from Baumgartner et al. (2014)
%
%   DEMO_BAUMGARTNER2014(flag) demonstrates how to compute and visualize 
%   the baseline prediction (localizing broadband sounds with own ears) 
%   for a listener of the listener pool and the median plane using the 
%   sagittal-plane localization model from Baumgartner et al. (2014).
%
%   Figure 1: Baseline prediction
% 
%      This demo computes the baseline prediction (localizing broadband 
%      sounds with own ears) for an exemplary listener (NH58).
%
%      Predicted polar response angle probability of subject NH58 as a  
%      function of the polar target angle with probabilities encoded by
%      brigthness.
