Hi, does anyone know how to change the width of the error bars produced using ErrorListPlot? Here is the table of data I'm using
 
  ppy = Table[{{(k + 574)*2 \[Pi]/(1*4000), pmy[[k]]}, 
        ErrorBar[sdy[[k]]]}, {k, 1, 191}];
Then I write
ErrorListPlot[ppy, PlotMarkers -> {Automatic, 1.5}
I can't seem to change the width of the error bars produced. Any ideas?
