%DATA_BAUMGARTNER2014  Data from Baumgartner et al. (2014)
%   Usage: data = data_baumgartner2014(flag)
%
%   DATA_BAUMGARTNER2014(flag) returns data from Baumgartner et al. (2014)
%   describing a model for sound localization in sagittal planes (SPs)
%   on the basis of listener-specific directional transfer functions (DTFs).
%
%   The flag may be one of:
%
%     'pool'      DTFs and calibration data of the pool. This is the
%                 default.
%
%     'baseline'  Same as 'pool', but also with experimental data for
%                 baseline condition.
%
%   The fields in the output contains the following information
%
%     .id         listener ID
%
%     .S          listener-specific sensitivity parameter
%
%     .Obj        DTF data in SOFA Format
%
%     .pe_exp     experimental local polar RMS error
%
%     .qe_exp     experimental quadrant error rate
%
%     .target     experimental target angles
%
%     .response   experimental response angles
%
%     .itemlist   experimental item list. Columns denote:
%                 1:4 ... azi_target,ele_target,azi_response,ele_response
%                 5:8 ... lat_target,pol_target,lat_response,pol_response
%                 9   ... F/B-Confusion resolved pol_response
%
%   Requirements: 
%   -------------
%
%   1) SOFA API from http://sourceforge.net/projects/sofacoustics for Matlab (in e.g. thirdparty/SOFA)
% 
%   2) Data in hrtf/baumgartner2014
%
%   Examples:
%   ---------
%
%   To get all listener-specific data of the pool, use:
%
%     data_baumgartner2014('pool');
%
%   To get all listener-specific data of the pool including experimental 
%   baseline data, use:
%
%     data_baumgartner2014('baseline');
