How to remove an artifact from a plot

I'm using Mathematica 6.0 and when I use the following notebook entry

Test=Table[{x,(1/2)+(Cos[2*2*Pi*x]/2)*(E^-(x^2)+(1/2)*0.1*E^-
((x-12)^2)+(1/2)*0.05*E^-((x-27)^2)+(10^-3)*E^-((x-280)^2))},
{x,-10,40,0.05}];ListPlot[Test,PlotRange->All,Joined->True,Frame-
>True,FrameLabel->{"Pathlength Mismatch (2\[CenterDot]m mm)"," Signal
Strength "},BaseStyle->{FontFamily->"Garamond",FontSlant-
>"Italic",FontSize->14}]

in addtion to the plot I want, I get a horizontal line across the
whole plot at 0.2.  This sort of artifact also appears occasionally in
Mathematica 5.1.

Does anyone know why it appears?

Does anyone know how to get rid of it?

Thanks very much,

John Feth
