%   Output parameters:
%     data.id    : listener ID
%     data.mtx   : experimental data matrix conaining 9 colums
%                  col 1: target azimuth
%                  col 2: target elevation
%                  col 3: response azimuth
%                  col 4: response elevation
%                  col 5: lateral angle of target
%                  col 6: polar angle of target
%                  col 7: lateral angle of response
%                  col 8: polar angle of response
%
%   `data_majdak2013ctc(condition)` returns listener-specific experimental
%   data from Majdak et al. (2013) testing localization performance in
%   sagittal planes for repeated HRTF measurements motivated by CTC binaural
%   synthesis.
%
%   The *condition* flag may be one of:
%
%     'A'   First HRTF measurement. This is the default.
%     'B'   Second HRTF measurement.
