%   DATA_MAJDAK2013(condition) returns listener-specific experimental data
%   from Majdak et al.  (2013) testing localization performance in sagittal
%   planes for low-pass filtered and spectrally warped DTFs.
%
%   The condition flag may be one of:
%
%     'BB'   Broadband DTFs (baseline condition). This is the default.
%     'LP'   Low-pass filtered (at 8.5kHz) DTFs
%     'W'    Spectrally warped (2.8-16kHz warped to 2.8-8.5kHz) DTFs
%

%     sound localization performance with spectrally warped and band-limited
