Velocity vectors are displayed in the central window, while the histograms of each component are in the lower left windows, see Fig. [uvmat_fig]. The arrow length is automatically set by default. It can be adjusted by the edit box '''[!VecScale]''' in the frame '''[Vectors']''' on the right hand side. 23 '''** Vectors''' 24 25 To read the velocity field, open it with the GUI ''''uvmat''''.

The thresholds for such color display can be adjusted from 0 to 1 (perfect image correlation) in the frame''' [Vectors]''', using the boxes '''[!ColCode1] ''' and '''[!ColCode2]''', or equivalently by the corresponding sliders '''[Slider1]''' and '''[Slider2] '''.
