    123123The 2D calibration is used as a reference horizontal grid with a grid height of[[BR]]- z = 80.8 cm for PCO1[[BR]]- z = 58.2 cm for PCO2

    127129The  calibration is checked with a calibration ruler (images saved in  CALIB_RULER) to see that the transition between the two cameras is  smooth.
     
    154156The cameras still have to be adjusted. After that is done, we take photos with the calibration grid in the horizontal and in 3D with both cameras that are fixed on the roof. With PIV, we conduct the calibration of both cameras as described in 4.1.

    158 To verify the calibration, we took photos with both cameras with one ruler to see if the calibrations of the cameras agree (which it does!). Then, we added a wall into the tank to prevent the water of the freshwater experiments to return to the source. The laser height was adjusted.
