%data_hassager2016 Externalization ratings as a function of spectral smoothness
%   Usage: data = data_hassager2016;
%         
%   Output parameters:
%     data : structure containing the listeners' ratings for the 
%            direct-sound condition with the following fields:
%
%            - B*: Vector with the eleven bandwidth factors (in ERB).
%
%            - angle*: Vector with the two source angles (in degrees).
%
%            - rating*: An 11-by-2 matrix with the externalization ratings.
