    1717= PIV on the parietal plume =
    1818Choose the following parameters:
    19 pair j=1-2 for Civ1 and Civ2 : it minimises the time interval which is needed to cpature the large velocity in the plume.
    20 CorrBox x,y=(5 31) which optimizes the resolution in x (5 pixels)
    21 Search x, y=(25 55) which allows for a larger velocity component along y .
    22 auto-grid Dx=2, Dy=10, consistent with CoorBox (about half the box size).
    23 Mask selected, with name .../Dalsa1.mask/mask_plume.png .
    24 For Civ2, same parameters CorrBox, auto-grid and Mask.
    25 For patch and Fix, default parameters.
     19- pair j=1-2 for Civ1 and Civ2 : it minimises the time interval which is needed to capture the large velocity in the plume.
     20- CorrBox x,y=(5 31) which optimizes the resolution in x (5 pixels)
     21- Search x, y=(25 55) which allows for a larger velocity component along y .
     22- auto-grid Dx=2, Dy=10, consistent with CoorBox (about half the box size).

     25- For patch and Fix, default parameters.

    2727= PIV on the interior =
     28Select the pair j=1-3 to deal with the small velocities (considering that the parietal plume has been masked). Then use the default parameters.

    2930= merging data on a common grid =
