function [h]=plot_ziegelwanger2013(Obj,data,type,color,ele,ch,time,style,width)
%plot_ziegelwanger2013 plot time-of-arrival
%   Usage: plot_ziegelwanger2013(Obj,data,type,color,ele,ch,time,style,width)
%
%
%   Input parameters:
%       Obj   : SOFA object
%       data  : Input data
%       type  : Plot type
%       color : Line color
%       ele   : Elevation [deg]
%       ch    : Channel Index
%       time  : Flag (1...time vector [ms] 0...[samples])
%       style : Linestyle
%       width : Linewidth
% 
%   Output parameters:
%       h: figure handle
%
%   Estimates the Time-of-Arrival for each column in input data hM and corrects 
%   the results with a geometrical model of the head.
%
%   Examples:
%   ---------
% 
%   To plot the modelled TOA in the horizontal plane after using
%   ziegelwanger2013, use:
%
%       plot_ziegelwanger2013(Obj,Obj.Data.Delay,1,'b',0,1,1);
