%
%   DATA_JOERGENSEN2011 returns measured change of SRT tested by Joergensen 
%   and Dau (2011). Average and standard deviation across listeners.
%
%   The flag may be one of:
%
%     'fig5' : The measured change in SRT (open squares), averaged across 6 
%              normal-hearing listeners, as a function of the reverberation 
%              time, T30 (0s, 0.4s, 0.7s, 1.3s, or 2.3s). 
%              The mean SRT in the reference condition was -3 dB. 
%              Model predictions are indicated by the filled squares. The 
%              linear correlation coefficient (q) and RMSE is indicated in 
%              the upper left corner.
%     'fig6' : DSRT (left ordinate) as a function of the over-subtraction 
%              factor a (0, 0.5, 1, 2, 4, or 8)
%              for 4 normal-hearing listeners (open squares) and 
%              sEPSM predictions (filled squares). The right ordinate (with 
%              a reversed scale) shows the corresponding sSTI values as filled 
%              gray circles. These values are, however, not converted to DSRT 
%              values since these would be outside the left ordinate scale.
