Plot legend data in ListStreamPlot

Hello,
My main question is: what is the data that the legend bar shows in the ListSteramPlot?

I am trying to visualize a flow filed by ListSteramPlot. The magnitude of the velocity, I mean u^2+v^2 is between zero and one. But the data shown in the plot legend is from 0 to 500!

Hi,
Thank you for your response. Here is my code.

flowdata = 
      Import["/Users/pmb5727/Projects/Drop_wall/flowData.dat", "Table"];
    Dimensions[flowdata]
    
    flowfield = 
      Partition[#, 2] & /@ 
       Table[{flowdata[[i, 1]], flowdata[[i, 2]], flowdata[[i, 3]], 
         flowdata[[i, 4]]}, {i, 1, Length[flowdata]}];
    ListStreamPlot[flowfield, PlotLegends -> Placed[Automatic, Above], 
     PlotRange -> {{-2.0, 2.0}, {-1.5, 2}}, AspectRatio -> 3.5/4]
