+To read the velocity field, open it with the GUI  ''''uvmat''''.

 The vector color indicates the quality of the image correlation maximum leading to each vector, blue is excellent, green average, red poor. 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] '''.
